Design And Implementation Of An Rf Data Communication System, Aung K. Soe

Honors Theses

Located just 8 miles northeast of Union College is Ballston Lake, a unique lake, which offers excellent research opportunities for faculty and students. The south basin of the lake is permanently stratified, and there has been no intermixing between water layers for thousands of years. The lower water layers contain no oxygen (anoxic). The Union College Geology Department is interested in a ten year study of Ballston Lake. Currently, there is no commercially available automatic system for collecting and transmitting data from a sensor package at the bottom of the lake to the lake shore and finally to Union College …

Effects Of Species, Water, And Nitrogen On Competition Among Three Prairie Grasses, Jerry L. Weatherford, Randall W. Myster

The Prairie Naturalist

We conducted an experiment to investigate effects of species, water (W), and nitrogen (N) on competition among little bluestem (Schizachyrium scoparium), sideoats grama (Bouteloua curtipendula), and indiangrass (Sorghastrum nutans). All biomass parameters and the root:shoot ratio of little bluestem were reduced by the presence off 1 of 2 other species, and its shoot biomass and total biomass were both increased by addition of N. Root and shoot biomass of sideoats grama were reduced by the presence of indiangrass and its total biomass was reduced by the presence of itself, whereas its shoot biomass was increased by addition of W at …

Determination Of Selected Heavy Metals In Some Creeks In A Tennessee City., Ann Ejimole Item

Electronic Theses and Dissertations

Concentrations of Ni, Cu, Zn, Fe, Cd, and Pb were determined in six different creeks within a city in Tennessee using Atomic Absorption Spectrophotometer. Mean concentrations of Ni, Cu, Zn, Cd, Pb, and Fe in the sites examined reveal that they exceed the USEPA recommended limits. High concentrations of Cu (0.130 mg/L), Zn (13.7 mg/L), Ni (0.267 mg/L), and Cd (0.010 mg/L) were observed in site B and Fe (3.01 mg/L) in site E relative to other sites. The concentration of Pb (0.795 mg/l) was higher in site A. Higher concentrations of Cu, Zn, and Fe were detected in samples …

Numerical Evaluation Of Subsurface Soil Water Evaporation Derived From Sensible Heat Balance, Masaru Sakai, Scott B. Jones, Markus Tuller

Plants, Soils, and Climate Faculty Publications

A recently introduced measurement approach allows in situ determination of subsurface soil water evaporation by means of heat-pulse probes (HPP). The latent heat component of subsurface evaporation is estimated from the residual of the sensible heat balance. This heat balance method requires measurement of vertical soil temperature and estimates of thermal properties for soil water evaporation determination. Our objective was to employ numerically simulated thermal and hydraulic processes using constant or diurnally cycled surface boundary conditions to evaluate and understand this technique. Three observation grid spacings, namely, 6 mm (tri-needle HPP), 3 mm (penta-needle HPP) and 1 mm, along with …

Ab Initio Investigation Of Hydrogen Bonding And Network Structure In A Supercooled Model Of Water, Lei Liang, Paul Rulis, Lizhi Ouyang, Wai-Yim Ching

Mathematical Sciences Faculty Research

The hydrogen bond (HB) and network structure in a large periodic model of 340 water molecules are investigated by ab initio methods. This model has a density of 1.00 g/cc, very small distortions of O–H bond length and H–O–H bond angle, and the peak positions in the radial distribution functions in close agreement with experiment. The 340 molecules can be classified into four groups according to the number of HBs quantitatively determined by the bond-order values. The percentages of water molecules with two, three, four, and five HBs are, respectively, 3.2%, 10.3%, 85%, and 1.5%, with an average HB number …

Revisiting The Lower Stratospheric Water Vapour Trend From The 1950s To 1970s, H. K. Roscoe, K. H. Rosenlof

United States Department of Commerce: Staff Publications

Previous work showed a near-continuous increase in stratospheric water vapour between the 1950s and 1990s from a variety of instruments, without recourse to fits between instruments. We reassess the trend from the earliest, the UK frost-point hygrometer, 1954–1976. An error in previous work omitted to transform values from ppmm to ppmv. When corrected, they fit more convincingly with measurements by later frost-point hygrometers. Minor instrument changes between the 1950s and 1970s do not introduce a potential bias to the trend but do increase its error. If the full 1970s data are included, the trend becomes 2.1 ± 0.8%/year (two-sigma).

Application Of The Water Poverty Index In Border Colonias Of West Texas, Marcelo Korc

Open Access Theses & Dissertations

This study applied the Water Poverty Index (WPI) in border colonias and other rural areas of west Texas. The colonias are mostly unincorporated communities located primarily in New Mexico and Texas along the border with Mexico and are characterized by high poverty rates and substandard living conditions. In Texas, access to drinking water and sanitation services has been identified as one of the most significant determinants of health in over 350 colonias with about 50 thousand residents.

The WPI is a multidimensional measure that links household welfare with water availability. WPI components were identified and prioritized by a wide range …

Nanoscale Condensation Of Water On Self-Assembled Monolayers, Michael James, Tamim A. Darwish, Simone Ciampi, Sven O. Sylvester, Zhaoming Zhang, Albert Ng, J Justin Gooding, Tracey L. Hanley

Australian Institute for Innovative Materials - Papers

We demonstrate that water is almost universally present on apparently dry self-assembled monolayers, even on those considered almost hydrophobic by conventional methods such as water contact goniometry. The structure and kinetics of nanoscale water adsorption onto these surfaces were investigated using X-ray and neutron reflectometry, as well as atomic force microscopy. Condensation of water on hydrophilic surfaces under ambient conditions formed a dense sub-nanometre surface layer; the thickness of which increased with exponentially limiting kinetics. Tapping mode AFM measurements show the presence of nanosized droplets that covered a small percentage (∼2%) of the total surface area, and which became fewer …

How Well Do Predators Adjust To Climate-Mediated Shifts In Prey Distribution? A Study On Australian Water Pythons, Beata Ujvari, Rick Shine, Thomas Madsen

Faculty of Science - Papers (Archive)

Climate change can move the spatial location of resources critical for population viability, and a species resilience to such changes will depend upon its ability to flexibly shift its activities away from no-longer-suitable sites to exploit new opportunities. Intuition suggests that vagile predators should be able to track spatial shifts in prey availability, but our data on water pythons (Liasis fuscus) in tropical Australia suggest a less encouraging scenario. These pythons undergo regular long-range (to .10 km) seasonal migrations to follow flooding-induced migrations by their prey (native dusky rats, Rattus colletti ). However, when an extreme flooding event virtually eliminated …
