      <title>PRINCIPLES OF THE CLASSIFICATION OF ARABLE SOILS</title>
      <link>https://trid.trb.org/View/121060</link>
      <description><![CDATA[THE GENETIC BASIS FOR THE CLASSIFICATION OF ARABLE SOD-PODZOLIC SOILS SHOULD BE THEIR SUBDIVISION ACCORDING TO DEGREE OF DEVELOPMENT OF THE SOD PROCESS /THE INTENSITY OF WHICH CORRESPONDS GENERALLY TO THE PROCESS OF CULTIVATION/, THE PODZOLIC PROCESS, AND SURFACE ABLATION. ZONAL SOIL FORMATION IN AGRICULTURAL SOILS MEANS THAT GRASSLAND AND ARABLE PODZOLIC SOILS SHOULD BE JOINED INTO SOME SORT OF LARGE TAXONOMIC UNIT OF CLASSIFICATION. NATURAL AND ARABLE SOILS SHOULD BE SUBDIVIDED AT DIFFERENT TAXONOMIC LEVELS FOR DIFFERENT SORTS OF THESE SOILS. FURTHER SUBDIVISION OF THE GENERAL GROUP OF ARABLE SOILS OF THE FOREST ZONE SHOULD BE BASED ON A GEOGRAPHIC-GENETIC CLASSIFICATION. ONLY WHEN THIS IS DONE WILL IT BE POSSIBLE TO DEFINE THE ARABLE SOILS ACCORDING TO THEIR DEGREE OF CULTIVATION. THIS PROBABLY SHOULD FOLLOW DIVISION INTO GENERA, WHICH, OF COURSE, ARE DISTINGUISHED ON THE BASIS OF THE SOIL-FORMING PARENT MATERIAL. /AUTHOR/]]></description>

      <title>IN-SERVICE ROUGHNESS OF NEW TECHNOLOGY ANTIFOULING PAINTS ON FOUR TEST SHIPS: FISCAL YEAR 1985 PROGRESS REPORT</title>
      <link>https://trid.trb.org/View/387767</link>
      <description><![CDATA[The British hull roughness analyzer has been used to measure the roughness of new technology antifouling paints while in service. The analyzer has provided data on the changes in roughness of fourteen new antifouling paints applied to the hulls of four test ships.  The mode and median values, together with their percent frequency based on an established cut-off point, have been used to discern the contribution of paint roughness to total ship roughness. Preliminary findings indicate that most ablative paints appear to be ablating with decreasing roughness while maintaining a surface free of calcareous fouling.]]></description>

      <title>AIRFIELDS ON ANTARCTIC GLACIER ICE. INTERIM REPORT</title>
      <link>https://trid.trb.org/View/303513</link>
      <description><![CDATA[The physical characteristics of blue-ice ablation areas in Antarctica are described and some representative ablation rates are given.  The possibilities for using blue-ice areas as airfields are outlined and exploratory surveys are mentioned.  Site details are given for icefields at Mount Howe, Mill Glacier, Patriot Hills, Rosser Ridge, Mount Lechner, S1 near Casey station, and on the Ross Ice Shelf near McMurdo station.  The surface roughness of blue ice is discussed, microrelief surveys are presented for Mount Howe and Patriot Hills, and spectral analyses are used to develop relations between bump height and wavelength.  U.S. military specifications for the roughness limits of various types of runways are summarized and graphical comparisons are made with the roughness analyses for Mount Howe and Patriot Hills.  Special machines for smoothing ice runways are discussed and design specifications are developed.  Some notes on ground facilities and ground transport are included.  Appendices give discussions of weather patterns in the Transantarctic Mountains and methodology for making spectral analyses of surface roughness.  It is concluded that glacier-ice airfields for conventional transport aircraft can be developed at low cost in Antarctica. Recommendations for further work are offered.]]></description>

      <title>HEAT TRANSFER PROBLEMS IN ADVANCED GAS TURBINES FOR NAVAL APPLICATIONS</title>
      <link>https://trid.trb.org/View/57830</link>
      <description><![CDATA[The report covers heat exchanger studies stressing measurements of local heat transfer coefficients by a method based on the heat and mass transfer analogy. Local ablation rates are obtained on a model covered with napthalene and from these heat transfer rates are deduced through the analogy. Impingement cooling and porous wall heat transfer have also been investigated. A number of studies in film cooling were also completed: Experiments covered measurements in a cascade, effects of free stream conditions and of laminar boundary layer. A laser-Doppler setup was used to measure local and instantaneous velocities at the exit cross-section of a gas turbine combustor and turbulence intensities were derived. (Author)]]></description>

      <title>ARCTIC ICE DYNAMICS JOINT EXPERIMENT. ICE DYNAMICS</title>
      <link>https://trid.trb.org/View/9952</link>
      <description><![CDATA[The report contains several papers related to ice motion. The first paper describes an experiment to measure the surface tilt of an ice-covered ocean using a hydrostatic leveling system.  The second paper discusses the distribution of ice (by age, thickness, and hummockedness) in the Arctic resulting from accumulation, ablation, and export of ice.  The third and fourth papers are translations of Soviet research on ice floe motion and the drift of ice fields.  Also included in the Bulletin are abstracts of two papers dealing with thermodynamic modeling of sea ice.]]></description>

      <title>MORAINIC SOIL DEPOSITS AND THEIR USE IN LOWER COST ROADS</title>
      <link>https://trid.trb.org/View/120348</link>
      <description><![CDATA[AN ATTEMPT IS MADE TO DETERMINE THE GEOLOGICAL NATURE AND ENGINEERING BEHAVIOR OF THE TILLS IN MORAINES. DETAILS ARE GIVEN OF INVESTIGATIONS INTO THE TEXTURAL CHARACTERISTICS OF ABLATION TILLS, OPTIMUM VALUE OF PERCENTAGE FINES, DRY DENSITY, CRUSHING OF AGGREGATES DURING COMPACTION, AND BEARING CAPACITY. FROM THE WORK CARRIED OUT TO DATE, MORAINIC SOIL DEPOSITS APPEAR TO FALL SHORT OF THE IDEAL ROAD CONSTRUCTION MATERIAL ON THREE MAIN POINTS: LACK OF BINDER, NEED OF HIGH COMPACTIVE EFFORT TO OBTAIN ACCEPTABLE C.B.R. VALUES, AND SUSCEPTIBILITY TO FROST HEAVE. /TRRL/]]></description>
