Antibiotic Effects On Coliform Enumeration, Keith Leonard Wozniak
Antibiotic Effects On Coliform Enumeration, Keith Leonard Wozniak
Masters Theses
The inhibitory effects of Bacillus polymyxa on Escherichia coli were studied. Significant coliform inhibition was observed. The inhibitory agent (presumably polymyxin) was active against coliforms after a one hour holding time. Different suspending menstrua were analyzed for their effects on coliform inhibition. It was observed that Peptone water provided the highest recovery of coliforms while phosphate buffer provided less protection. Two methods of enumeration were also studied as to their ability to quantify coliforms inhibited by B. polymyxa. Comparable inhibition was shown using both methods. No significant differences exist between the Standard Plate Count and Membrane Filter techniques. Overall, …
The Effects Of Xanthine And Adenosine Analogs On Rat Pup Diaphragmatic Contractility, Liam C. Farrell
The Effects Of Xanthine And Adenosine Analogs On Rat Pup Diaphragmatic Contractility, Liam C. Farrell
Masters Theses
Methylxanthines are commonly used in the treatment of respiratory disorders such as asthma, apnea of prematurity and Cheyne-Stokes respiration. Recently, certain methylxanthines have been found to potentiate the contraction of the diaphragm and increase contraction strength of the fatigued diaphragm. The mechanism of action of the methylxanthines is unknown. Three theories have been proposed but each has its supportive and negative points. One theory is that methylxanthines inhibit cyclic AMP phosphodiesterase (PDE) which facilitates contraction by increasing cyclic AMP levels in the cell. Another theory is that methylxanthines antagonize adenosine, thus blocking the adenosine-induced inhibition of contraction. The third theory …
A Taxonomic Re-Evaluation Of Specimens Of The Genus Caloplaca In The E.L. Stover Herbarium Of Eastern Illinois University, Eric J. Cameron
A Taxonomic Re-Evaluation Of Specimens Of The Genus Caloplaca In The E.L. Stover Herbarium Of Eastern Illinois University, Eric J. Cameron
Masters Theses
The genus Caloplaca is the largest genus in the family Teloschistaceae. The 103 species in the genus greatly outnumber any other in the family. Lichens of the genus Caloplaca are usually orange to orange-yellow in color, and range from crustose to subfoliose in form. The orange color is due to an anthraquinone, parietin, the location of which is taxonomically important in this genus of lichens. In some species it occurs only in the apothecia, while in others it is found in both the apothecia and thallus. The spores of this genus are polarilocular, and the width of the isthmus is …
A Woody Understory Survey Of Baber Woods, Edgar County, Illinois, Jacqueline M. Spencer
A Woody Understory Survey Of Baber Woods, Edgar County, Illinois, Jacqueline M. Spencer
Masters Theses
The understory of Baber Woods, located in Edgar County, Illinois, was surveyed to see if sugar maple had increased enough in importance to consider implementing some type of forest management technique. Five 100 meter transects were randomly located in closed canopy areas throughout the woods. Specimens were removed from continuous 1 meter quadrats located along each line. Specimens were also removed from twenty 25 meter transects located in the open canopy areas. Species, age, height, diameter, and quadrat number were recorded for each specimen. The data was analyzed for age-height and age-diameter relationships, plus individuals per hectare, density, frequency, relative …
The Effects Of Frozen Storage And Repeated Freeze-Thawing On Salmonella In Varied Concentrations Of Waste Activated Sludge, Joseph Toman Jr.
The Effects Of Frozen Storage And Repeated Freeze-Thawing On Salmonella In Varied Concentrations Of Waste Activated Sludge, Joseph Toman Jr.
Masters Theses
Commonly, waste activated sludge is applied to farmland as a fertilizer supplement and soil conditioner. The use of waste activated sludge is not only an efficient way of sludge disposal, but also an economical one. Much concern has been raised about the safety of such a practice. Harmful pathogens, like Salmonella, are commonly present in waste material. Treatment at wastewater plants is successful in eliminating these organisms from final effluent, but the solids generated are full of indigenous microorganisms, including Salmonella.
Work of this paper attempts to determine the safety of the sludge product after simulated winter conditions …
