Studies on attitude control of small payloads of sounding rockets

Creator:: Melo, Ajax Barros de
Abstract:: This work has the purpose of presenting an approach to attitude control applicable for sun alignment on scientific payloads. As a primary source of information in order to obtain the alignment error signals, four solar cells are disposed about the body of the payload. As a secondary source a pair...

Identification of species and varieties of ryegrass (Lolium spp.)

Creator:: De Barros, Manoel Bernardo
Abstract:: The objective of this study was to investigate ryegrass seedling characteristics that, by themselves, or combined with presently known characters, could improve varietal identification tests. Thirteen characters were studied on 30 varieties of Lolium multiflorum Lam., L. perenne L., L. rigidum Gaud, and L. hybridum Hausskn., including leaf size and...

Data report : trace element, Sr isotope, and Ge/SI composition of fluid and sediments in ridge-flank low-temperature hydrothermal environments

Creator:: Hulme, Samuel M., Wheat, C. Geoffrey, Coggon, Rosalind M., and McManus, James
Abstract:: The data presented in this report demonstrate significant improvements in the ability to constrain trace element and Sr isotopic concentrations in sediments overlying ridge-flank hydrothermal systems. Improved sampling methods orchestrated by the Integrated Ocean Drilling Program (i.e., advanced piston coring and anoxic sample processing) enabled the collection of reactive pore...

Spatial and temporal variability of late Neogene Equatorial Pacific carbonate : ODP Leg 138

Creator:: Hagelberg, T. K., Pisias, Nicklas G., Mayer, L. A., Shackleton, N. J., and Mix, Alan C.
Abstract:: High resolution, continuous records of GRAPE wet bulk density (a carbonate proxy) from Ocean Drilling Program Leg 138 provide one the opportunity for a detailed study of eastern equatorial Pacific Ocean carbonate sedimentation during the last 6 m.y. The transect of sites drilled spans both latitude and longitude in the...

Benthic foraminiferal stable isotope stratigraphy of Site 846 : 0-1.8 Ma

Creator:: Mix, Alan C., Le, J., and Shackleton, N. J.
Abstract:: A stable-isotope stratigraphy at Site 846 (tropical Pacific, 3°06'S, 90°49'W, 3307 m water depth), based on the benthic foraminifers Cibicides wuellerstorfi and Uvigerina peregrina, yields a high-resolution record of deep-sea δ¹⁸O and δ¹³C over the past 1.8 Ma, with an average sampling interval of 3 k.y. Variance in the δ¹⁸O...

Sediment depths determined by comparison of grape and logging denisty data during Leg 138

Creator:: Mix, Alan C., Harris, Sara E., Hagelberg, T. K., Pisias, Nicklas G., and Shackleton, N. J.
Abstract:: Establishing true depths of recovered sediments is critical to determining sedimentation rates for high-resolution paleoclimatic studies. We have corrected the composite depth scale, which accounts for the entire continuous sedimentary sequence, so that sediment depths are consistent with logging depths, or "true" depths. We accomplished this by taking advantage of...

Assessing the effect of a fuel break network to reduce burnt area and wildfire risk transmission

Creator:: Oliveira, Tiago M., Barros, Ana M. G., Ager, Alan A., and Fernandes, Paulo M.
Abstract:: Wildfires pose complex challenges to policymakers and fire agencies. Fuel break networks and area-wide fuel treatments are risk-management options to reduce losses from large fires. Two fuel management scenarios covering 3% of the fire-prone Algarve region of Portugal and differing in the intensity of treatment in 120-m wide fuel breaks...
