Community Geothermal Technology Program: Fruit drying with geothermal energy. Final report

Description: Largest problem was lack of proper recording and controlling instrumentation. Agricultural products tested were green papaya powder, banana slices, and pineapple slices. Results show that a temperature of 120 F is a good drying temperature. Papaya should be mature green and not overly ripe; banana ripeness is also important; and pineapple slice thickness should be very uniform for even drying. Geothermal drying is feasible. Figs, tabs.

Current drive by intense microwave pulses

Description: The advent of high-peak-power pulsed microwave sources opens possibilities for novel current-drive schemes in tokamaks. Four such schemes are considered: accelerating phase-space buckets, overlap of relativistic electron-cyclotron harmonics, beat-wave generation and burnthrough of intense lower-hybrid waves. These schemes are found to offer one or more of the following advantages over their continuous-power counterparts: improved efficiency, improved access to the core plasma, and precise contr… more

The Effect of Chemical Additives on the Synthesis of Ethanol

Description: The objective of this research is to elucidate the role of various chemical additives on ethanol synthesis over Rh- and Ni-based catalysts. Chemical additives used for this study will include S, P, Ag, Cu, Mn, and Na which have different electronegativities. The effect of additives on the surface state of the catalysts, heat of adsorption of reactant molecules, reaction intermediates, reaction pathways, reaction kinetics, and product distributions is/will be investigated by a series of experime… more

Eigenmodes of a random walk on a 2-D lattice torus with one trap

Description: The complete set of eigenvalues and eigenmodes is elaborated for a random walk on a two-dimensional N )times) N square lattice torus with one trap site. The eigenvalue closest to unity is found to have an asymptotic expansion in N; the leading behavior is lambda )approximately) 1 )minus) ..pi.. (2N/sup 2/ log N) )plus) O(N log N)/sup )minus/2). In general, the eigenvalues and eigenmodes for this problem are constructed from those for a random walk on the same lattice containing no trap. The deg… more

Enhanced durability and reactivity for zinc ferrite desulfurization sorbent

Description: AMAX Research Development Center (AMAX R D) has been investigating methods for enhancing the reactivity and durability of the zinc ferrite desulfurization sorbent. Zinc ferrite sorbents are intended for use in desulfurization of hot coal gas in integrated gasification combined cycle (IGCC) or molten carbonate fuel cell (MCFC) applications. For the present program, the reactivity of the sorbent may be defined as its sulfur sorption capacity at the breakthrough point and at saturation in a bench-… more

Legal Implications of the Contagious Disease or Infections Amendment to the Civil Rights Restoration Act, S.557

Description: This report discusses the civil rights restoration act, S. 557, as it passed the House and Senate. This provision would most likely be interpreted as codifying the existing standards relating to section 504 interpretation concerning discrimination against individuals with handicaps.

Measurements of optical loss in transparent solids using a novel spectrometer based on optical cavity decay

Description: Recent advances in High Average Power (HAP) solid state lasers and the development of new concept lasers with the potential of ultra- high average power output have put increasing demands on the transparency of optical window materials. To gain a better understanding of the current status of window materials and to direct research toward more nearly transparent materials, we have constructed an optical characterization facility with the purpose of making quantitative optical loss measurements i… more

Preliminary report on shallow research drilling in the Salton Sea region

Description: During two shallow thermal drilling programs, thermal measurements were obtained in 56 shallow (76.2 m) and one intermediate (457.3 m) depth holes located both onshore and offshore along the southern margin of the Salton Sea in the Imperial Valley, California. These data complete the surficial coverage of the thermal anomaly, revealing the shape and lateral extent of the hydrothermal system. The thermal data show the region of high thermal gradients to extend only a short distance offshore to t… more

Quark gluon plasma: Overview and experimental results from E-735

Description: A brief review of the phenomenology associated with the effort to produce and observe quark-gluon plasma in particle collisions is presented. E-735 has taken data during the 1987 Tevatron-Collider run at /square root/s = 1.8 TeV in pursuit of this goal. Results in the correlation of < p/sub t/ > with multiplicity for charged particles and p/sub t/ distributions for ..lambda../sup o/ and /bar Lambda//sup o/ are presented. 32 refs., 10 figs., 2 tabs.
