The Ouarzazate Basin is the southern foreland basin to the High Atlas Mountains in Morocco. The sedimentary fill records a sequence dating from the Eocene to Pleistocene that records the interplay between tectonics and climate. This study presents the first stable isotope and facies analyses of the Middle to Late Miocene Aït Ibrirn lacustrine Member (Aït Kandoula Formation). These data test whether the basin was internally draining and enable the development of palaeoenvironmental models for...

Corrosion is derived from the Latin word “corrosus” meaning away. It can be defined as “the destruction or deterioration and consequent loss of metals through chemical or electrochemical attack by the environment”. The process of corrosion is the transformation of pure metal into its undesired metallic compounds. The life time of metal gets shortened by the corrosion process. Most metals [except noble metals] occur in the form of their compounds such as oxides, sulfides, carbonates,...

Soil carbon (C) represents the largest terrestrial carbon stock and is key for soil productivity. Major fractions of soil C consist of organic C, carbonates and black C. The turnover rate of black C is lower than that of organic C, and black C abundance decreases the vulnerablility of soil C stock to decomposition under climate change. The aim of this study was to determine the distribution of soil C in different pools and impact of agricultural management on the abundance of different species....

While establishing the basis for a 'Technology 2000' product plan several years ago we plugged in the usual factors contributing toward product success: price/performance justifiable; profitable, warranting high quality maintenance, enhancement, and specific property improvement; narrow inventory requirements; and raw material integrable backwards with easily variable properties (molecular weight, functionality, and isomer control). We resolved this by selecting radical functional, low...

We have come up with a method which captures much of the experts' expertise in a dataflow design graph: Seamlessly connectable set of local and remote design tools; Seamlessly connectable web based design tools; and Web browser interface to the developing spacecraft design. We have recently completed our first web browser interface and demonstrated its...

Soil inorganic carbon (SIC) is currently not included in the list of key soil properties related to ecosystem services (e.g., provisioning, regulating, cultural, and supporting services). Soil inorganic carbon is a dynamic key soil property used in soil classification, taxonomy and fertility, therefore its inclusion in the framework of ecosystem services is important. With soils rapidly changing due to human use and climate change, the ecosystem services framework should include not only soil...

The focus of NASA's Search for Extraterrestrial Intelligence (SETI) Program is on microwave frequencies, where receivers have the best sensitivities for the detection of narrowband signals. Such receivers, when coupled to existing radio telescopes, form an optimal system for broad area searches over the sky. For a directed search, however, such as toward specific stars, calculations show that infrared wavelengths can be equally as effective as radio wavelengths for establishing an interstellar...

The aerodynamic damping moment in pitch was measured with a hovering helicopter rotor. Three kinds of model blades with different rigidity were tried. A flow visualization study was performed for the purpose of determining the relative position between the blade and the vortices in steady hovering state. The perfectly rigid rotor was determined. Aerodynamic damping moment in pitch was analyzed. A quasi-steady theory is devised. A simple formula for calculating the pitch damping derivative of a...

Two good syntheses of the rare tube silicate litidionite, NaKCuSi4O10, are reported. In one a 2:1:1:8 mole-ratio mixture of CuO, Na(2)CO3, K2CO3, and SiO2 is sintered and in the other a glass made from a mixture of these reagents in the same mole ratios is devitrified. The structures of the ion in this silicate and those in other known tube silicates are discussed in terms of their relationships to each other and to the ions in other silicates. It is pointed out that many latticework tubes like...

The interaction between oxygen and selected molten carbonates has been examined in this project using density functional theory (DFT) modeling. In particular, B3LYP/6-31G(d) has been used for all geometry optimization, charge calculation, and orbital analysis. Three oxygen species including molecular oxygen (O2), superoxide (O2 -), peroxide (O2 2-) and atomic oxygen ion (O2-) are considered. The combination of oxygen with single carbonate (CO3 2-) forms molecular complexes, CO5 2- and CO4 2-,...

Anion exchange membranes (AEMs) are being developed for potential use in fuel cell systems which include portable power applications. In a fuel cell, these membranes transport hydroxide ions from the cathode to the anode. If carbon dioxide is present, carbonate and bicarbonate ions can form, displacing the hydroxide ions. Among the challenges this presents, the carbonate and bicarbonate are less mobile than the hydroxide and therefore the ionic conductivity of the membrane suffers. A procedure...

Results from a numerical and experimental study that illustrate the effects of selected cutout reinforcement configurations on the buckling and failure response of compression-loaded composite cylindrical shells with a cutout are presented. The effects of reinforcement size, thickness, and orthotropy on the overall response of compression-loaded shells are described. In general, reinforcement around a cutout in a compression-loaded shell can retard or eliminate the local buckling response and...

First, the Na2O-CO2-H2O system was examined for evidence of gaseous NaHCO3 or other carbonates that may be important as sinks for sodium in the atmosphere. Second, the mass spectrum and ionization efficiency curves...

Although well controlled this...
