Doctoral Dissertations

The rates of disappearance of 1,1-dimethyl-3-(a, a, a-trifluoro-m-toly1) urea (fluometuron) and the propylene glycol butyl either esters and a triethylamine salt of (2, 4, 5-trichlorophenoxy) acetic acid (2, 4, 5-T) from the application site in field plots and lysimeters were determined. Residual herbicide concentrations were estimated for field plot soil, runoff water collected in the plots after rainfall, and permanently impounded drainage water from the plots. Bioassays, spectrophotometry, and gas-liquid chromatography were utilized to detect residual concentrations of the three compounds. Linear and multicurvilinear equations were developed from known concentrations of the herbicide for predictions of ...


Changes In Tenderness And Collagen Of Beef Semitendinosus Muscle Heated At Two Rates, Marjorie Porter Penfield Dec 1973

Changes In Tenderness And Collagen Of Beef Semitendinosus Muscle Heated At Two Rates, Marjorie Porter Penfield

Doctoral Dissertations

Tenderness, an important quality attribute of meat, is affected by many factors, including rate of heating. The purpose of this investigation was to study the changes occurring in beef semitendinosus muscle and intramuscular connective tissue heated at rates comparable to oven roasting at 93 and 149°C. The sequence of changes occurring during heating was followed by evaluating samples heated to four end points, 40, 50, 60, and 70°C. Cores of meat and isolated connective tissue samples in buffer were heated in a water bath "programmed" to produce the desired rate of heating.

Ultrastructure Of Inclusion Bodies In The Transitional Epithelium Of Monkey Urinary Bladder, Alan B. Weckerling Dec 1973

Ultrastructure Of Inclusion Bodies In The Transitional Epithelium Of Monkey Urinary Bladder, Alan B. Weckerling

Theses & Dissertations

It has been noted that hematoxylin-eosin stained surface cells in the transitional epithelium of certain animals occasionally contain acidophilic inclusion bodies. These can be observed in monkey kidney pelvis, ureter, urinary bladder, and urethra. In one species of monkey, Macaca fascicularis, the inclusion bodies are quite prevalent and apparently are not related to any pathologic or experimental condition. They are highly refractile under the light microscope, a property which often indicates structures below the resolving power of the microscope. This study was designed to explore the composition and structure of these inclusion bodies. Procedures were selected to detect the presence ...

The Effects Of Speed Of Web On The Coat Weight Variation In Blade Coating, Pak Kee Lee Dec 1973

The Effects Of Speed Of Web On The Coat Weight Variation In Blade Coating, Pak Kee Lee

Paper Engineering Senior Theses

Numerous works have been done on the investigation of coat weight variations by various researchers. The mechanism of the variation, in a given base stock, is explained by the two models - the hydrodynamic pressure which is a strong function of the web speed, and the visco-elastic or normal force. For a given coating color, viscosity is a function of the web speed which causes the shearing action to take place. Increasing the speed will cause an increase in hydrodynamic pressure as well as visco-elasticity, which tend to lift up the blade and thus a higher coat weight will be obtained ...

The Effects Of Atropine On The Growth And Respiration Of Two Species Of Bacteria Normally Inhabiting The Human Gastro-Intestinal System, Mary M. Ramos Oct 1973

The Effects Of Atropine On The Growth And Respiration Of Two Species Of Bacteria Normally Inhabiting The Human Gastro-Intestinal System, Mary M. Ramos

Theses & Dissertations

It is the purpose of this study to determine whether the drug atropine has an effect on bacteria found normally inhabiting the human body, most specifically the gastrointestinal system. Atropine is one of the oldest drugs in medicine. It is derived from the roots and leaves of solanaceous plants such as henbane and Jimson weed. Atropine is often termed a belladonna alkaloid because it can also be found in the deadly nightshade plant, Atropa belladonna. Atropine is a highly competitive antagonist of acetylcholine at receptor sites in smooth muscles, cardiac muscle, and various glandular cells (5). Therefore, its effects are ...


A Test Of The Simple Recessive Hypothesis For The Inability To Taste Phenyl-Thio-Urea: A Family Study, Susan I. Wolf Aug 1973

Isolation And Characterization Of A High Energy Iron-Sulfur Protein From Mammalian Cells, Beth Feland Aug 1973

Isolation And Characterization Of A High Energy Iron-Sulfur Protein From Mammalian Cells, Beth Feland

Doctoral Dissertations

A sulfur-containing protein (S-protein) was proposed to be an intermediate in the sulfation of cellular constituents containing ester sulfate after it was observed that S-protein isolated from the particulate fraction of the cell was unaffected by avitaminosis E, the stress of malathion intoxication or the level of inorganic sulfate in the diet. The present investigation was undertaken in an attempt to identify the cellular role of the S-protein in sulfate utilization.

The role of the S-protein as a possible intermediate in the sulfation of ester sulfates was determined using both a natural sulfate acceptor, mucopolysaccharide, and an artificial sulfate acceptor ...

The Relation Of The Membrane Potential Of Nitella To Photosynthetic Processes And External Conditions, Shay-Whey Margaret Koh Aug 1973

The Relation Of The Membrane Potential Of Nitella To Photosynthetic Processes And External Conditions, Shay-Whey Margaret Koh

Environmental Science and Ecology Theses

In Nitella cells the H+ extrusion pump is believed to be the mechanism for generating the electric potential across the plasmalemma. Raven and Smith (1973) have proposed that the primary role of the H+ pump is to control the internal pH, with the level of the membrane potential (Em) varying, depending on the H+ pumping rate. The level of the resting potential would also depend upon the magnitude of the return current of H+ into the cell; this in turn is dependent on the external pH.

The above hypothesis was tested by imposing external conditions which would lead to ...


The Relation Of The Membrane Potential And Resistance Of Nitella To Ion Fluxes, Thomas E. Ryan Aug 1973

The Relation Of The Membrane Potential And Resistance Of Nitella To Ion Fluxes, Thomas E. Ryan

Environmental Science and Ecology Theses

The results of this study indicate membrane resistance of Nitella cannot be related to passive fluxes of ions as classical interpretation suggests. When a hyperpolarizing current of about 0. 6 µ amp cm-2 was passed through the membrane, with 42K present in the external solution, it was found that 50% of the current was carried by K+. The increase in K+ influx was 40 times the value predicted by the Goldman passive model for the observed changes in potential. The large transference number for K+ is not in agreement with Kitasato's conclusion that 95% of the cationic ...
