Superacid Catalyzed Coal Conversion Chemistry. 1st and 2nd Quarterly Technical Progress Reports, September 1, 1983-March 30, 1984. [Model Compound Consisting of 2 Benzene Rings Connected With Various Bridging Units Such as Alkylidene, Ether, Sulfide, Etc]

Description: In our laboratories we have previously developed a mild coal conversion process. This involves the use of a superacid system consisting of HF and BF/sub 3/ in presence of hydrogen and/or a hydrogen donor solvent. In order to understand the chemistry involved in the process of depolymerization of coal by the HF:BF/sub 3/:H/sub 2/ system we are carrying out a systematic study of a number of coal model compounds. The model compounds selected for present study have two benzene rings connected with … more

Dependence of liquefaction behavior on coal characteristics. Part V. Penetration of solvent vapor into coal particles. Final technical report, March 1981-February 1984

Description: The investigation of the sorption of solvent vapor into high volatile bituminous coal at temperatures up to 175/sup 0/C indicates that the solvent weight gain involves a complex coupling of several phenomena including adsorption, sorption into the coal matrix, capillary condensation and extraction into the condensed vapor phase. It appears that the sorption in untreated coal is dominated by capillary condensation induced by solvent extraction. As a result, an equilibrium state is not attainable… more

Davydov solitons in polypeptides

Description: The experimental evidence for self-trapping of amide-I (CO stretching) vibrational energy in crystalline acetanilide (a model protein) is reviewed and related to A. S. Davydov's theory of solitons as a mechanism for energy storage and transport in protein. Particular attention is paid to the construction of quantum states that contain N amide-I vibrational quanta. It is noted that the N = 2 state is almost exactly resonant with the free energy that is released upon hydrolysis of adenosine triph… more

Dissolving coal at moderate temperatures and pressures. Final report, August 20, 1982-September 30, 1984. [Benzylamine]

Description: The main objectives of this research were to make Illinois No. 6 coal liquid or soluble with inexpensive reagents (e.g., solvolysis with methanol and acids), without high pressure equipment, and to see if our soluble products would be more reactive than whole coal in liquefaction processes. These efforts are unpromising. However, efforts to make coal soluble by oxidation with nitric acid gave encouraging results. When Illinois No. 6 and Wyodak coals were allowed to stand in sunlight for 282 day… more

C/sub 4/ photosynthesis in Euphorbia degeneri and E. remyi: a comparison of photosynthetic carbon metabolism in leaves, callus cultures and regenerated plants

Description: Based on analysis of /sup 14/CO/sub 2/ fixation kinetics and assays of enzymes related to C/sub 4/ metabolism (NAD-ME, NADP-ME, NAD-MDH, NADP-MDH, AST, ALT), leaves and regenerated plants of Euphorbia degeneri exhibit a modified NADP-ME-type photosynthesis. Apparently, both aspartate and malate are used for transport of CO/sub 2/ to bundle sheath cells. Callus grown on either non-shoot-forming or shoot-forming media fixes CO/sub 2/ into RPP-cycle intermediates and sucrose, as well as malate and… more

Corrosion in SRC-I coal liquid distillation towers. SRC-I quarterly technical report, April-June 1981. Supplement

Description: During pilot plant operations for the SRC-I process, severe corrosion developed in the solvent fractionation towers. This high corrosion rate on carbon and types 304 and 316 stainless steel occurred when the pilot plant was processing coal with 0.15 to 0.39 wt % chloride. Subsequent stream analysis revealed that synergistic effects of inorganic chloride, phenols, and nitrogen compounds were responsible for corrosion most severe in the 200/sup 0/C (400/sup 0/F) boiling range. Liquid analysis als… more

Cell proliferation kinetics and radiation response in 9L tumor spheroids

Description: Cell kinetic parameters, including population doubling-time, cell cycle time, and growth fraction, were measured in 9L gliosarcoma spheroids. These parameters were studied as the spheroids grew from 50 ..mu..m to over 900 ..mu..m in diameter. Experiments relating the cell kinetic parameters to the radiation response of 9L spheroids were also carried out. The major findings were that the average cell cycle time (T/sub c/), is considerably longer in large spheroids than in exponentially-growing m… more

Control points within the cell cycle

Description: Evidence of the temporal order of chromosomal DNA replication argues favorably for the view that the cell cycle is controlled by genes acting in sequence whose time of expression is determined by mitosis and the amount of nuclear DNA (2C vs 4C) in the cell. Gl and G2 appear to be carbohydrate dependent in that cells starved of either carbohydrate of phosphate fail to make these transitions. Cells deprived of nitrate, however, fail only at Gl to S transition indicating that the controls that ope… more

Determination of oil/water and octanol/water distribution coefficients from aqueous solutions from four fossil fuels.

Description: Liquid fossil fuels, both petroleum and synthetically derived oils, are exceedingly complex mixtures of thousands of components. The effect of many of these energy-related components on the environment is largely unknown. Octanol/water distribution coefficients relate both to toxicity and to the bioaccumulation potential of chemical components. Use of these partition data in conjunction with component concentrations in the oils in environmental models provides important information on the fate … more

Ovine model for studying pulmonary immune responses

Description: Anatomical features of the sheep lung make it an excellent model for studying pulmonary immunity. Four specific lung segments were identified which drain exclusively to three separate lymph nodes. One of these segments, the dorsal basal segment of the right lung, is drained by the caudal mediastinal lymph node (CMLN). Cannulation of the efferent lymph duct of the CMLN along with highly localized intrabronchial instillation of antigen provides a functional unit with which to study factors involv… more
