Measurement Of The Effects Of Food Preparation Activities On The Microclimate Of The Snowball Dining Room Area Of Mammoth Cave, Kelly Kaletsky Jun 1992

Measurement Of The Effects Of Food Preparation Activities On The Microclimate Of The Snowball Dining Room Area Of Mammoth Cave, Kelly Kaletsky

Masters Theses & Specialist Projects

The stability of Mammoth Cave’s microclimate has never undergone extensive investigation. The Snowball Dining Room area was chosen to measure the microclimate of the cave and to determine if food preparation, human presence and surface temperature variations alter this microclimate. Three portable weather stations containing a temperature / humidity probe, datalogger and microbarograph were placed in various locations along three passageways leading away from the dining room. Readings were taken 24 hours per day for four months. Plotting temperature readings in graph form show a correlation between temperature of the passageway and distance from the dining room.


A Climatology Of Transition Season Colorado Cyclones: 1961-1990, Gregory D. Bierly May 1992

A Climatology Of Transition Season Colorado Cyclones: 1961-1990, Gregory D. Bierly

All-Inclusive List of Electronic Theses and Dissertations

Colorado cyclones have been the subject of many meteorologic and climatologic investigations, but few studies have examined cyclone behavior with a specific focus on a comparison of the spring and fall transition seasons in the upper level westerlies. Periods of change in the number of planetary waves lead to a rearrangement of the longwave pattern in the westerlies and an increased frequency of troughs in the southwestern United States. Short wave disturbances andjor jet maximum moving through the long wave pattern create the potential for Colorado cyclogenetic events and also increasing the frequency of severe weather resultant from these events. …

A “Drastic” Evaluation Of The Ground-Water Pollution Potential Of Karst Terrain: Lost River Ground-Water Basin, Warren County, Kentucky, David Baize Apr 1990

A “Drastic” Evaluation Of The Ground-Water Pollution Potential Of Karst Terrain: Lost River Ground-Water Basin, Warren County, Kentucky, David Baize

Masters Theses & Specialist Projects

Karst terrains, such as the Lost River Karst Ground-Water Basin, are extremely vulnerable to ground-water contamination. Seven physical factors: depth to water, recharge, aquifer media, soil media, topography, impact of the vadose zone, and hydraulic conductivity, are evaluated using the DRASTIC system to determine the ground-water pollution potential of the study area. A numerical value is calculated for each of the seven factors, and a map layer for each factor is produced. These layers are then “added” together to produce a DRASTIC ground-water pollution potential map. The effectiveness of each factor in evaluating the pollution potential of karst terrain is …

Pioneers Of Modern Geography: Translations Pertaining To German Geographers Of The Late Nineteenth And Early Twentieth Centuries, Robert C. West

GreyZone

This collection of English translations samples the writings and/or critiques thereon of six important German geographers of the late nineteenth and early twentieth centuries: those of August Meitzen, Eduard Hahn, Otto Schliiter, Alfred Hettner, Siegfried Passarge, and Karl Sapper. Each of these scholars influenced in various ways the course of modem geographical thinking and instruction in German universities, and their methodologies were also adopted in part by professional geographers in other European countries and in the United States. Four of them—Hahn, Schliiter, Hettner and Passarge— were students of Ferdinand von Richthofen, often considered the “father” of professional geography in Germany. …
