Alternative advanced power systems designed to operate a 500-ton submersible have been examined with respect to overall weight and volume fractions. Two-week and one-month missions, with and without the conventional “at-sea” recharge capability, were considered to evaluate the impact of advanced technologies on non-nuclear submarine design. Candidate air-breathing, primary-power systems studied included Diesel, Closed-Brayton Cycle (CBC), and fuel cells. A number of options for underwater operation were based upon high-energy reactants replenlshable from Base supplies. Another set of options was considered based upon using JP-S fuel with “at-sea” rechargeable secondary power systems, including thermal-energy storage, advanced lithium-sulfur batteries, or flywheels. Replenlshable high-energy reactant systems were, on average, lower in weight and volume than the rechargeable systems for the same submerged-mission profile. Moreover, the replenlshable systems permitted an extended tactical encounter with a maximum duration of 8 to 17 hours at speeds of 30 knots without the need to resurface and recharge a secondary energy storage device. The lowest-weight rechargeable systems in the order of increasing weight were the CBC engine with advanced lithium-sulfur battery, the CBC engine with carbon-block (thermal energy storage), and the Diesel engine with advanced lithium-sulfur battery. The rechargeable systems required unacceptable weight fractions in both missions. The high-energy (replenlshable from Base supplies) systems, with the exception of the heavy acid fuel cell using LOX, were all acceptable candidates for application in the two-week mission. Only the CBC engine with a llthium-sulfurhexaflaoride heat source, the lowest-weight system in both mission groups, was acceptable for the one-month mission.

Inc Dr. Robert A. Frosch born in New York City on 22 May 1928
attended Columbia University from which he received his B.A. degree in 1947 his M.A. degree in 1949 and his Ph.D. degree in 1952 all in the field of Theoretical Physics. While completing his studies for his doctorate he joined Columbia's Hudson Laboratories in 1951 and worked on naval research projects as a Research Scientist until 1958 when he became the Director Hudson Laboratories a post he held until 1963. From 1965 to 1966
he was Deputy Director Advanced Research Projects Agency (APRA) Department of Defense (DOD) having first joined ARPA in 1963 as the Director for Nuclear Test Detection the position he held until 1965. Since 1969 he also has served as the DOD member of the Committee for Policy Review National Council of Marine Resources and Engineering Development and in 1967 and 1970 as the Chairman of the U.S. Delegation to the Intergovernmental Oceanographic Commission meetings at UNESCO in Paris. In addition he was the Assistant Secretary of the Navy for Research & Development from 1966 to 1973 Assistant Executive Director of the United Nations Environment Program
with the rank of Assistant Secretary General of the United Nations from 1973 to 1975 and Assistant Director for Applied Oceanography at the Woods Hole Oceanographic Institution from 1975 until mid-1977.In June 1977
he became the Administrator of the National Aeronautics and Space Agency (NASA) the position he held prior to joining the American Association of Engineering Societies (AAES) Incorporated. On 20 January 1981 he was elected to his present post as President AAES. Additionally he was the Sea Grant Lecturer for the Massachusetts Institute of Technology in 1974 and currently is a National Lecturer for Sigma Xi. During his distinguished career
Dr. Frosch has been the recipient of numerous awards among which are the Arthur S. Flemming Award in 1966 the Navy Distinguished Public Service Award in 1

The 40Ca and 58Ni (d,6Li) reactions have been studied at 54 MeV bombarding energy. Four final states in 36Ar and eight in 45Fe were identified and angular distributions were measured. A exact finite range DWBA analysis has been carried out and spectroscopic factors have been compared to those extracted from the data in the reaction (3He, 7Be).

This is a publication of results obtained by the collaboration experiment of the Brazil and Japan Emulsion Group over a period of nearly ten years since 1962. It is divided into five parts.I. Introductiongives a short description of the emulsion chambers exposed at Mt. Chacaltaya Laboratory (5200 m), Bolivia, ranging from Câmara No. 1 of 0.4 m2up to Câmara No. 15 of 44.2m2, with a brief historical review of the collaboration experiment. Main part of the present results are obtained with Câmara No. 12 (6m2) and No. 13 (9.8m2), both of which have the producer layer for nuclear interactions in the chamber ***. Morphological Strides on Cosmic-ray Componentsgive the results on frequency, energy spectrum and zenith angle distribution of the electromagnetic and the nuclear-active components at Chacaltaya. The vertical flux for the electromagnetic component is (2.66·10-9/cm2sec sterad)·(E/1012eV)- βwith β= 2.07 ± 0.10, covering energy region of 2·1011eV ∼ 5 · 1013eV. Ratio of a flux value of the electromagnetic component to that of the nuclear-active component of the same visible energy is ∼ 0.56, constant over the concerned energy ***. Fire-ball Studies on C-jetsgive detailed analysis on 85 events of local nuclear interactions with ΣEγ≥ 3 TeV occurred in the producer layer. High energy r-rays produced in the interaction are described in the integral form asNγexp(-NγEγ/ΣEγ) withNγ= 8 ± 1. All of the results on energy spectrum, angular distribution,pTdistribution andpT- θγcorrelation show that those γ-rays are products of an isotropic intermediate state (a fire-ball) with momentum distribution,Nγexp(-pγ*/p0)(pγ*/p02)dpγ*withNγ= 8 ± 1,p0= 82 ± 15 MeV in its rest system. A fire-ball analysis is made on individual 75 C-jets with the observed γ-ray multiplicity equal to or greater than 4. Seventy one events are found to show emission of a fire-ball. Their experimental mass spectrum has a peak at \mathfrakMγ∼ 1.2 GeV, giving the average value as ≪\mathfrakMγ> = 1.28

The modes of Pacific decadal-scale variability (PDV), traditionally defined as statistical patterns of variance, reflect to first order the ocean's integration (i.e., reddening) of atmospheric forcing that arises from both a shift and a change in strength of the climatological (time-mean) atmospheric circulation. While these patterns concisely describe PDV, they do not distinguish among the key dynamical processes driving the evolution of PDV anomalies, including atmospheric and ocean teleconnections and coupled feedbacks with similar spatial structures that operate on different timescales. In this review, we synthesize past analysis using an empirical dynamical model constructed from monthly ocean surface anomalies drawn from several reanalysis products, showing that the PDV modes of variance result from two fundamental low-frequency dynamical eigenmodes: the North Pacific–central Pacific (NP-CP) and Kuroshio–Oyashio Extension (KOE) modes. Both eigenmodes highlight how two-way tropical–extratropical teleconnection dynamics are the primary mechanisms energizing and synchronizing the basin-scale footprint of PDV. While the NP-CP mode captures interannual- to decadal-scale variability, the KOE mode is linked to the basin-scale expression of PDV on decadal to multidecadal timescales, including contributions from the South Pacific.
