Tungsten Carbonyl Complexes Containing Positively Charged Phosphorus Ligands, Dilip Poonamchand Shah
Tungsten Carbonyl Complexes Containing Positively Charged Phosphorus Ligands, Dilip Poonamchand Shah
Masters Theses
Two positively charged complexes, (CO)5WP(C6H5)2CH2CH2-+P(C6H5)2(CH2C6H5) Br- and (CO)5W(C6H5)2PCH2+P(C6H5)2CH3 I-, were synthesized, and their carbonyl stretching frequencies and force constants were compared to those of the uncharged complexes, (CO)5WP(C6H5)2CH2CH2P(C6H5)2 and (CO)5WP(C6H5) …

Some Ecological Effects Of The Oil Industry On Farmland In East Central Illinois, Dale E. Fruendt
Some Ecological Effects Of The Oil Industry On Farmland In East Central Illinois, Dale E. Fruendt
Masters Theses
Between June, 1970 and July, 1971 a two square mile area in East Central Illinois served as a study area for the effects of the oil industry on farm land. Observations were made on several farms concerning the activity of oil companies and interviews with farmers were held. Two areas of farmland were given special attention. One was a clover field where salt water had flooded a portion of the field. The other area was a corn field where oil had flooded approximately eight acres of land. Random samples of invertebrates were taken in both of these areas as well …
A Comparative Limnological Study Of Three East Central Illinois Farm Ponds, Charles W. Furrey
A Comparative Limnological Study Of Three East Central Illinois Farm Ponds, Charles W. Furrey
Masters Theses
A comparative limnological study was conducted at three east central Illinois farm ponds between March 15 and September 18, 1970, to determine the incidence of nitrogen and phosphorus in the ponds resulting from agricultural sources. All ponds had corn, soybean, winter wheat cropping systems on their watersheds. Corn accounted for the greatest fertilizer application. One pond had significant numbers of livestock on its watershed that contributed high amounts of nitrogen and phosphorus to its waters. Limnological parameters measured at the surface, mid depth, and bottom of a ten foot water column in each pond were water temperature, dissolved oxygen, carbon …

Comparison Of Diffusion Coefficients Measured Electrochemically And Non-Electrochemically, Terry Dick Rotsch
Comparison Of Diffusion Coefficients Measured Electrochemically And Non-Electrochemically, Terry Dick Rotsch
Masters Theses
Diffusion coefficients of Co(en)3I3⋅H2O, FeCl3, and K3Fe(CN)6 were measured using the methods of polarography, chronopotentiometry, and diaphragm cell for the purpose of determining any relationships which may exist between these values. A major objective of the present study was to relate diffusion coefficients obtained by a simple non-electrotrochemical method to diffusion coefficients used in electrochemical techniques.
It was found that the polarographically determined diffusion coefficients were all 1.04 times larger than the chronopotentiometric values. This constant factor is probably due to viscosity differences tn the polarographic and chronopotentiometric solutions …
