Sea Turtle Response to Climate Change: Analyzing Current and Predicting Future Impacts on Populations, Habitat, and Prey Populations

With the prediction of devastating global climate change effects for the near future, scientists are expanding their research and understanding of some of the most severely affected organisms. Because sea turtles rely on both marine and terrestrial habitats for survival, and because coastal areas are already experiencing great losses due to sea level rising, human development, and pollution, all seven species are already listed as threatened under the Endangered Species Act. In this literature analysis, I examined the many factors that contribute to a sampling of the current sea turtle population status as well as scrutinized turtle adaptability to the changing environment. After developing a broad global view of the effects of climate change and human practices on worldwide sea turtle populations, I focused my study on the populations found in the waters of America as a continent, which included case studies of Costa Rica and Cape Cod Bay. In these two unique regions, various species experience diverse threats, including cold stunning, problems feeding, and nesting pressures. From this literature review in combination with my own independent research projects, I examined how some turtle populations would be affected by changing environmental and anthropological factors, and congruently formed my own conclusions and predictions about current population statuses and potential future implications. Though global climate change is causing sea level rise, and sand and air temperature increases, humans greatly impact both the vital marine and terrestrial environments of foraging and nesting sea turtles through ocean acidification, development, and over exploitation. The future of sea turtle population conservation and management relies on research and understanding of anthropogenic and climate change effects on marine and coastal habitats

The Dormant Second Amendment: Exploring the Rise, Fall, and Potential Resurrection of Independent State Militias

The term “militia” is polarizing, misunderstood, misapplied, and generally difficult for modern Americans to digest. That is not surprising, given the depth and breadth of American militia history and militias’ substantial evolution over four centuries. Historically, militia simply refers to a broad-based civic duty to protect one’s fellow citizens from internal and external dangers and is not limited to activities involving firearms. Reestablishing militia’s true meaning and purpose—and reinvigorating independent state militias in the United States to effect that purpose—has the potential to address states’ emerging financial and security gaps and to produce multiple other significant benefits, including recalibrating federalism. This article suggests a method for how best to reinvigorate independent state militias, addresses the major critique against doing so, and initiates a real discussion about the future of state militias—an issue conspicuously underdeveloped in scholarship today

Cluster Algebras and the Subalgebra Constructibility of the Seven-Particle Remainder Function

We review various aspects of cluster algebras and the ways in which they appear in the study of loop-level amplitudes in planar ${\cal N} = 4$ supersymmetric Yang-Mills theory. In particular, we highlight the different forms of cluster-algebraic structure that appear in this theory's two-loop MHV amplitudes---considered as functions, symbols, and at the level of their Lie cobracket---and recount how the `nonclassical' part of these amplitudes can be decomposed into specific functions evaluated on the $A_2$ or $A_3$ subalgebras of Gr$(4,n)$. We then extend this line of inquiry by searching for other subalgebras over which these amplitudes can be decomposed. We focus on the case of seven-particle kinematics, where we show that the nonclassical part of the two-loop MHV amplitude is also constructible out of functions evaluated on the $D_5$ and $A_5$ subalgebras of Gr$(4,7)$, and that these decompositions are themselves decomposable in terms of the same $A_4$ function. These nested decompositions take an especially canonical form, which is dictated in each case by constraints arising from the automorphism group of the parent algebra.Comment: 68 pages, 7 figures, 6 table

Thermophysical properties of sodium

Assessment is given of physical and thermodynamic properties of sodium. FORTRAN subroutine computes enthalphy and entropy of sodium in given state, and composition, molecular weight, volume, and compressibility factor of corresponding vapor. Tabular results for saturated liquid and vapor are presented for a 500-2500 degree F range

Process comparison study. MSFC Center Director's Discretionary Fund (CDDF)

A process comparison study was conducted using four different advanced manufacturing techniques to fabricate a composite solid rocket booster systems tunnel cover. Costs and labor hours were tracked to provide the comparison between the processes. A relative structural comparison of the components is also included. The processes utilized included filament winding, pultrusion, automated tape laying, and thermoplastic thermoforming. The hand layup technique is also compared. Of the four advanced processes evaluated, the thermoformed thermoplastic component resulted in the least total cost. The automated tape laying and filament winding techniques closely followed the thermoplastic component in terms of total cost; and, these techniques show the most promise for high quality components and lower production costs. The pultruded component, with its expensive tooling and material requirements, was by far the most expensive process evaluated, although the results obtained would not be representative of large production runs
