Altering Rules, Cumulative Voting, And Venture Capital, John F. Coyle

Utah Law Review

Legal scholars have long debated the proper balance betweenmandatory and default rules in corporate law. One group — the contractarians — maintain that corporatelaw should function as an off-the-rack set of default rules that approximate, as much as possible,the rules that the transacting parties would have agreed to if bargaining were costless. The contractarians are generally skeptical of mandatory rules because they interfere with the ability of the parties to decide for themselves how to organize their economic relationships. Another group of scholars—the anti - contractarians — have argued that corporate law should seek to achieve certain regulatory objectives separate …

Robotics In The Classroom: The Effectiveness Of Robotics Based Curriculum In Stem Education, Mark Nall

Graduate Research Papers

Students learn best when they are engaged and are able to interact with their environment. They can build their own definition of concepts and themes, which are more meaningful because they are related to their own experiences and memories (Kolb, 1984). Simply put it all comes down to constructivism, which means a person builds knowledge and meaning from interactions between their experiences and ideas (the environment they work/play in and the people and objects they interact with). The purpose of this study is to find out how a middle school and high school constructivist robotics curriculum impacts students’ conceptual understanding …

Late Quaternary Chronostratigraphy Of The Aegean Sea Sediments: Special Reference To The Ages Of Sapropels S1?S5, Ekrem Bursi̇n İşler, Richard Nicholas Hiscott, Ali̇ Engi̇n Aksu

Turkish Journal of Earth Sciences

Four sapropel layers (S1, S3, S4, and S5) are identified in five 6-10-m-long piston cores collected from the Aegean Sea basins. A chronostratigraphic framework is established for the last ~130 ka using benthic and planktonic foraminiferal oxygen isotope curves, total organic carbon contents, volcanic ash layers, and limited radiocarbon dates. These data show that the onsets of sapropels S3, S4, and S5 in the Aegean Sea basins were not synchronous, highlighting the heterogeneity of the Aegean Sea basins in terms of rapid versus lagged responses to changing ocean-climate boundary conditions. In all cases, however, the development of sapropels S3, S4, …

Turkish Journal of Earth Sciences

The Yenipazar deposit of volcanogenic sulfide occurrence, situated approximately 9 km SW of Yenipazar, is hosted in quartz-muscovite schists and gneiss. Following the Late Cretaceous, the quartz-mica schists and gneiss have been altered to clay minerals, resulting in important kaolin deposits. The clay deposits consist mainly of halloysite, kaolinite, smectite, illite, muscovite, chlorite, and α-quartz. Biotite, alunite, jarosite, pyrite, hematite, calcite, low cristobalite, and feldspar are present in minor amounts. In places, some mixed-layer clays, such as kaolinite/smectite and smectite/illite, are also observed within the clay deposits. Barite is present in a few clay samples. α-Quartz is the dominant silica …

Nummulitic Facies Of The Crimean-Caucasian Region, Ekaterina A. Lygina, Pavel A. Fokin, Ludmila F. Kopaevich, Anatoly M. Nikishin, Elena V. Yakovishina

Turkish Journal of Earth Sciences

The nummulitic limestones of Crimea and the southwestern Caucasus, often interpreted as "nummulite banks", formed carbonate platforms throughout most of the Ypresian-Lutetian. Such deposits were accumulated in shallow warm-water basins of Crimea and the Caucasus, which differed from each other by the structure of the basement and the hydrodynamic regime. The Crimean carbonate platform was relatively flat and was formed mainly within quiet hydrodynamic conditions below the fair-weather wave base (less than 50 m). The facies changes within it reflect variations in water depth. Facies distinguished there form the nummulite bank, its lee-side slope, the shelf plain in the rear …

Source Mechanism Analysis Of Single-Well Microseismic Data Using Full-Wavefield Moment Tensor Inversion, Trudy Watkins

LSU Master's Theses

Receiver angular coverage of microseismic sources occurring during hydraulic fracturing treatments is an important factor to consider when interpreting moment tensor inversion results. A horizontal receiver array can provide greater angular coverage of vertical failure planes than a vertical receiver array. The source orientation can be accurately determined if the array samples both sides of the failure plane. However, the compensated-linear-vector-dipole (CLVD) mechanism can be overestimated by up to ~40% for double-couple (DC) sources and the isotropic mechanism can be overestimated by ~70% for CLVD sources. Source mechanism constraints on the moment tensor inversion are used to mitigate the lack …

These cores were subject to multiple tests, including gamma bulk density scans, grain size analysis, and loss-on-ignition, in order to identify the lithology and stratigraphy. In addition, 137Cs and 14C dating techniques were employed in order to construct …

A Model Compound Study In Syngas Tar Reforming, Jaren Lee

LSU Master's Theses

Biomass or coal gasification are promising processes for renewable energy. However, a major operating problem in gasification is what to do with syngas byproducts such as H2S and tars (heavy hydrocarbons) that cause catalyst deactivation downstream. Studies have shown that rare earth oxides (REOs) doped with transition metals are promising catalysts for tar reforming in the presence of sulfur.(R. Li, Roy, Bridges, & Dooley, 2014) In Chapter 1, propane is studied as a model compound for tar reforming with transition metal-doped (e.g., Mn, Fe) REOs. These are compared to a typical commercial Ni/Al2O3 catalyst. The results showed that REO/TM catalysts …
