The Effect Of Various Concentrations Of Alkali With The Adsorption Of Calcium Ions Onto Oleic Acid, Thomas J. Mcapline

Paper Engineering Senior Theses

The purpose of this thesis was to find an optimum condition for the formation of the precipitated calcium soaps. The system investigated included the range of alkali addition of 0 to 1.2 pounds per one hundred gallons (#/100 gal.). A direct relationship between the adsorption with an increasing alkali concentration to a maximum of 145 parts per million calcium ion adsorbed to 833.5 ppm oleic acid when .225 (#/100 gal.) is applied. It shows that any higher concentration of an alkali will level out the maximum calcium adsorption to approximately 140 ppm.

It was also found that the alkali demand …

Comparative Study Of Flotation And Sidehill Washing Stages In Deinking Coated Magazine Stock, Joseph M. Korepta

Paper Engineering Senior Theses

This is a study comparing the effectiveness of removing ink particles, consumption of water, and the retention of coating and/or filler pigments in deinked pulp between the flotation washing method and the counter-current sidehill washing method. Coated magazine waste paper was deinked using 5.3% Sodium Hydroxide at 190°F. The washing stage of both methods was carried out at a .9% consistency and a temperature of 30°C. The results of the study indicate that the flotation method of washing deinked pulp removed the majority of ink particles but did not remove the coating and filler pigments. The …

The Effects Of Temperature On Retention, Michael D. Holt

Paper Engineering Senior Theses

The purpose of this thesis was to study the effects of temperature and concentration of retention aids on retention. This had been a debatable issue between northern and southern paper mills because of their temperature differences.

The retention studies were performed with the dynamic drainage jar and the pilot paper machine at Western Michigan University with good agreement in both cases.

It was found that increasing temperature when using different retention aids had a considerable effect on first-pass retention. The effect of temperature on retention was found to depend on the ionic charge of the retention aid. The cationic polymer …

The Effects Of Ph On Alkali-Swellable Latex Binder Coating Systems, Larry N. Justen

Paper Engineering Senior Theses

Introduction

In recent years there has been a growing demand for the use of synthetic latexes as sole binders in coating formulations. This had been brought about by the shortage of supply and changing prices of natural binders like casein and protein. Synthetic latex binders require no cooking; this increased energy saving over starch becomes more important as fuel prices rise. Synthetic latex systems are easy to handle and they can be combined easily to fit different requirements.

Most synthetic latex systems need a thickener and water retention aid to achieve the right viscosity and flow properties. The new alkali-swellable …

The Effects Of Variable Double Disk Refining Action On Sheet And Fiber Properties, Gary Flohr

Paper Engineering Senior Theses

The purpose of this project was to evaluate several operating variables of the newly installed Western Michigan University Jones DD 3000 refiner. The operating variables were refiner load in amperes, throughput rate in gallons per minute, and disk speed in revolutions per minute.

On the fiber level, Canadian Standard Freeness was most dependent upon the load and somewhat less dependent upon the tonnage rate and speed. The tonnages used were 4.8, 9.6, and 14.4 T/D. At 9.6 T/D, the refiner used the least HPD/T per 100 ml C.S.F. drop throughout the 300-500 ml C.S.F. range. At 4.8 and 9.6 T/D, …

Susceptibility At High Inoculum Of Penicillin-Resistant Staphylococcus Aureus To Six Cephalosporins, Andres Suarez, Ramon Del Busto, Edward L. Quinn, Donald Pohlod

Henry Ford Hospital Medical Journal

Six cephalosporins (currently available for clinical use or undergoing clinical trials) were tested by tube dilution method against high inoculum (10⁷ colony forming units) of 37 strains of penicillin resistant Staphylococcus aureus. 3.1 μg/ml of cephalothin inhibited 100% of strains while higher concentrations of cefoxitin, cephapirin, cefamandole, cephalexin and cephradine were required. The percent of strains with minimal inhibitory concentration higher than 3.1 μg/ml ranged between 10.8% (cefoxitin) and 100% (cephradine). These findings support the observation that cephalothin is less susceptible to inactivation than the other cephalosporins. Although the exact clinical implication of these findings has not been established, …

High Dose In-Continuity Irradiation Of Para-Aortic And Pelvic Nodes For Carcinoma Of The Prostate. The First Three-And-One-Half Years, Joel Elliot White, Murray Boles

Henry Ford Hospital Medical Journal

A technique for treating the para-aortic nodes to a high dose of irradiation in continuity with the pelvis has been developed at Henry Ford Hospital and recently described by one of the authors. The "nine-field technique" was initially used in late 1973 to treat two patients with advanced prostatic carcinoma who had grossly involved para-aortic nodes. Since that time, 16 additional patients with carcinoma of the prostate, one patient with carcinoma of the urinary bladder, and one patient with carcinoma of the cervix have been treated by this technique. This paper analyzes sequelae and complications of the technique and mentions …

Rationale And Results Of Anatomic Repair Of Esophageal Hiatus Hernia, Conrad R. Lam

Henry Ford Hospital Medical Journal

A logical method of repair of esophageal hiatus hernia based on anatomic principles was proposed nearly 25 years ago by the late Phillip Allison. There was general agreement that his operation had advantages, but because of a disappointing number of recurrences and problems with reflux, more complicated operations were devised. Some of these involved plication of the stomach around the lower esophagus (Nissen, Belsey). In a series of 562 operations for hiatus hernia at the Henry Ford Hospital, there has been no significant deviation from the Allison technic. Complicating lower esophageal rings (Schatzki) have been excised. There has been no …

Use Of Technetium-99 Myocardial Scanning For Identification Of Intraoperative Myocardial Infarctions, Virender D. Parekh, Sidney Goldstein, Donald Magillican, Daniel Marks

Henry Ford Hospital Medical Journal

Technedum 99m stannous pyrophosphate (TcPyP) myocardial scans were obtained in 42 selected nonconsecutive patients within 12 days following open heart operations for both valve replacement (19 patients) and coronary bypass (23 patients) procedures. The scans were correlated with elevation of serum lactic dehydrogenase, glutamic oxalacetic transaminase and the electrocardiograms obtained serially in the postoperative period. TcPyP scan was more specific than enzyme studies and it was more sensitive than the electrocardiogram. All new Q waves were associated with a positive scan but there were five positive scans which were not associated with new Q waves. Myotomy and direct surgical trauma …

Telorchis Gutturosi Sp. N. (Trematoda: Telorchiidae) From Graptemys Pseudogeographica Gray In Nebraska, With Reports Of Additional Species Of Trematodes From Nebraska Turtles, Daniel R. Brooks, Monte A. Mayes

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

One species of digenean is described and 8 others reported from turtles in Nebraska. Telorchis gutturosi, described from Graptemys pseudogeographica, resembles T. stossichi, T. pseudoaculeatus, and T. pleroticus in having an acetabulum significantly smaller than the oral sucker, but differs by possessing a pharynx which is as large as the acetabulum and having the ovary only 1/10 the body length from the acetabulum. Telorchis necturi is considered the senior synonym of T. cryptobranchi; Graptemys pseudogeographica is a new host. Hapalorhynchus stunkardi is reported for the first time since its description. Based on new morphological evidence, …

Two Tetraphyllidean Cestodes From The Freshwater Stingray Potamotrygon Magdalenae Dumeril 1852 (Chondrichthyes: Potamotrygonidae) From Colombia, Daniel R. Brooks, Thomas B. Thorson

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

Two new tetraphyllidean cestodes are described from the freshwater stingray Potamotrygon magdalenae from Colombia. The new genus Potamotrygonocestus is proposed for P. magdalenensis, which differs from Pedibothrium by having a bilobed rather than X-shaped ovary, and simple rather than bifid hooks. It further differs from Pachybothrium hutsoni by having bothridial hooks inserted immediately posterior to an accessory sucker rather than inserted in the middle of a thick muscular pad. Potamotrygonocestus magdalenensis is unique among known tetraphyllideans by possessing vitellaria which are compact, cylindrical bands in the lateral portions of the middle of the proglottid. The second new species, Rhinebothrium …

Department of Animal Science: Faculty Publications

These data included the records of 818 purebred gilts and sows of Duroc, Hampshire and Yorkshire breeding mated to produce all purebreds and all possible two-way crosses. A total of 212 gilts were slaughtered 30-day postbreeding (72 purebred matings and 140 crossbred matings) to evaluate ovulation rate, number of live embryos, average embryo length and embryo survival rate. A total of 450 litters (161 purebred and 289 crossbred) were farrowed to evaluate litter size, litter weight and average pig weight at O, 21 and 42 days postfarrowing. Litters were farrowed in the spring and fall of 1971 and 1973 and …

Aspects Of Some Compacted Campground Ameliorating Practices, Keith Foster

Electronic Theses and Dissertations

The purpose of this study was to determine if the direct mechanical manipulation of compacted campground soils, with and without the addition of organic materials and the planting of grasses, had any long lasting effect on the amelioration of these deteriorated campsites. An attempt was also made to determine the natural recovery time for East Texas sandy loam soils using the campground closure method. Closure or partial (seasonal) closure of campsites reduced compaction to an acceptable level in three years. Roto-tilling alone was the least effective treatment. Roto-tilling and the addition of bark or chips to maintain the loose soil …

Leaf Epidermal Transmittance Of Ultraviolet Radiation And Its Implication For Plant Sensitivity To Ultraviolet-Radiation Injury, Ronald Robberecht

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Leaf epidermal transmittance of ultraviolet radiation (280-400 nm) was examined in several plant species to determine the capability of the epidermis to attenuate solar ultraviolet radiation. Epidermal samples were mechanically isolated and examined with a spectroradiometer/integrating sphere for transmittance. A survey of 25 species exposed to natural insolation was conducted. Although the species differed in life form, habitat type, and epidermal characteristics, epidermal transmittance was generally less than 10%. Ultraviolet radiation was attenuated 95 to 99% in more than half of the species. In 16 species, flavonoid and related pigments in the epidermis accounted for 20 to 57% of the …

Effects Of Time Of Application Of Glyphosate In The Control Of Johnsongrass, Marlin Moody

Masters Theses & Specialist Projects

Investigations were conducted to determine the effects of the herbicide glyphosate and its time of application on the control of johnsongrass.

Johnsongrass plots were divided into areas designated undisturbed, spring plowed, and clipped. These areas were compared to determine differences in control of johnsongrass when using glyphosate with different management procedures. Glyphosate was applied at weekly intervals and treatment effects were statistically analyzed. There were three replications of each treatment.

It appears from the results that:

1. Glyphosate kills approximately 100% of the johnsongrass topgrowth regardless of the application date.

2. Height of the johnsongrass plant at the time of glyphosate application …
