Here, we study very low-altitude orbits (down to 50 km) in a high-degree and order model of the Martian gravity field. We apply Prony's Frequency Analysis (FA) to characterize the time variation of their orbital elements by computing accurate quasi-periodic decompositions of the eccentricity and inclination vectors. -

GYPSUM AND CARBON AMENDMENT’S INFLUENCE ON SOIL PROPERTIES, GREENHOUSE GAS EMISSIONS, GROWTH AND NUTRIENT UPTAKE OF RYEGRASS (Lolium perenne) DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Maninder Kaur Walia, M.S. Environment and Natural Resources Graduate Program The Ohio State University 2015 Dissertation Committee: Warren A. Dick, Advisor Rattan Lal Brian K. Slater Frederick C. Michel,Jr. Copyrighted by Maninder Kaur Walia 2015 Abstract Gypsum is a source of calcium and sulfur that improves the physical and chemical properties of the soil. With the benefits associated with gypsum use and the increased availability of synthetic gypsum, its application to soil in Ohio and the Midwest is increasing. Several studies have focused on the effect of gypsum on soil properties. However, little is known about how gypsum affects C stocks in soils. In this study, in addition to gypsum, we also treated the soil with glucose to create a high level of CO2 in the soil profile, and contrasted that with the more slowly released C from plant residues. The overall goal of this dissertation research was to evaluate the effect of plant residues, glucose and gypsum on the growth and nutrient uptake of ryegrass, chemical properties (including total and inorganic C stock) and physical properties of two contrasting soils in Ohio (Wooster silt loam and Hoytville clay loam). Specific objectives of this research were to quantify the effect of (1) gypsum and plant residues on greenhouse gas emissions, (2) gypsum and C amendments on quality of leachate water, (3) gypsum and C amendments addition on C fractions in soils, (4) gypsum, plant residues and glucose addition on soil fertility, growth and nutrients concentrations of ryegrass and (5) gypsum, glucose and plant residues on selected soil physical properties and aggregate-associated C and N. -
Cold-Climate Landforms on Mars
CHAPTER 3 Landforms Indicative of Creep of Debris and Ice Among the large number of landforms related to the creep of ice and debris in periglacial environments on Earth, the most well-known landforms comprise rock glaciers and landforms related to gelifluction processes. While rock glaciers usually form relatively confined but well-distinct landforms, the latter contribute to a large extent to the general slope development in periglacial environments and are less distinct in their appearance. The author focuses here on rock glaciers and related landforms because of their size which allows comparison workwithlandformsonMarsandbecauseoftheirdirectconnectiontoso-calledMartianlobatedebrisaprons which are discussed in subsequent sections. Slope-forming processes in contrast to this, cover a much wider field that is characterized by an abundance of landforms that cannot be attributed to a distinct climatic envi- ronment unambiguously because of their transitional nature (e.g., Selby, 1982). Also, terrestrial slope-forming processes are not necessarily comparable to the Martian environment because of the nature of controlling fac- tors, such as vegetation and precipitation. The subsequent discussion of rock glaciers and related landforms on Earth will not only summarize some of the major scientific aspects but will also try to establish a connection to the Martian environment whenever possible. 3.1.
