Fish Feeding-Habit Studies From Tomales Bay, California, Stephen Robert Karl

University of the Pacific Theses and Dissertations

The Bat Ray, Myliobatis californica Gill, occurs from Oregon to the Gulf of California and is common in California bays during the spring and summer. MacGinitie (1935) observed that during its feeding activities, the Bat Ray can dig channels up to 1 meter wide, 50 cm deep and 4.5 meters long in benthic substrates. In intertidal sand flats in Tomales Bay, California, circular pits up to 1 meter in diameter and 20 cm in depth are made by Bat Rays in late summer. In some areas over 50% of the sand flat surface is covered with Bat Ray pits. This …

Revision Of The Antillean Bats Of The Genus Brachyphylla (Mammalia: Phyllostomatidae), Pierre Swanepoel, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Nongeographic and geographic variation have been analyzed in the genus Brachyphylla. which belongs to the Antillean endemic subfamily Phyllonycterinae of the family Phylloslomatidae. Males were found to be generally larger than females: therefore, the sexes were analyzed separately for geographic variation. External measurements except length of forearm were found to displaya high degree of individual variation. They were not used in subsequent analyses. Of cranial measurements, greatest length of skull and condylobasal length showed the least individual variation, whereas palatal length, postorbital breadth (in samples from west of the Mona Passage only), and rostral width at canines showed relatively …

Dose Patterns For ¹⁰⁶Ruo₄ Inhaled By Fischer-344 Rats, Gene E. Runkle

Biology ETDs

Ruthenium-106 is an abundant fission product radionuclide in the nuclear fuel cycle which has potential for release as ruthenium tetroxide. This study was designed to provide additional data needed to adequately assess the risk for humans potentially exposed to ¹⁰⁶RuO₄vapor. Fiscner-344 rats were given a nose-only exposure to ¹⁰⁶RuO₄ vapor to determine its distribution and retention patterns. The largest percentage of the initial body burden was found in the nasopharyngeal region of the respiratory tract. Ruthenium-106 deposited in this region was rapidly cleared and excreted in the feces. Less than 1% of the initial body …

Bacteriocin-Like Substances Produced By Rhizobium Japonicum And Other Slow-Growing Rhizobia, D. C. Gross, A. K. Vidaver

Department of Plant Pathology: Faculty Publications

Bacteriocin-like substances were commonly produced by slow-growing Rhizobium japonicum and cowpea rhizobia on an L-arabinose medium. Antagonism between strains of R. japonicum was not detected in vitro; however, such strains were often sensitive to some bacteriocins produced by cowpea rhizobia. Inhibitory zones (2 to 8 mm from colony margins), produced by 58 of 66 R. japonicum test strains, were reproducibly detected with Corynebacterium nebraskense as an indicator. Quantitative production was not related to symbiotic properties of effective strains, since nine noninfective strains and one ineffective strain produced bacteriocin. Eight R. japonicum strains that did not produce bacteriocin nevertheless formed effective …

Lichenometric Distribution Of Rhizocarpon Geographicum On Mt. Washington: A Relative Dating Tool., Paul Andrew Mayewski, Peter A. Jeschke

Earth Science Faculty Scholarship

Excerpt from summary, p. 83: In addition to marking the distribution of snowpatches and the relative age of patterned ground features, local departures from the regional lichenometric trend may also be used to define and relatively date: changes in the distribution of soils and vegetation, avalanche deposits, and abrasion of hiking trails. Lichenometric studies will be undertaken in the following year to date more precisely features and events on Mount Washington.

Review Of The Desert Pocket Gopher, Geomys Arenarius (Mammalia: Rodentia), Stephen L. Williams, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The desert pocket gopher (Geomys arenarius), which occupies a restricted geographic range in Texas, New Mexico, and Chihuahua, was examined for morphological variation. Univariate and multivariate analyses were used to determine age, sexual, individual, and geographic variation. Significant differences were found among different age classes and between sexes. Males displayed higher individual variation than females and external measurements were more variable than cranial measurements. Two subspecies--G. a. arenarius and G. a. brevirostris--were recognized after analyses of geographic variation.

The Effects Of Recycling On Fiber Characteristics, Michael B. Bekes

Paper Engineering Senior Theses

Recent trends in recycling indicate that future use will increase. This increase will bring a demand for the secondary fiber. Many technical questions have to be answered before recycling becomes an economical process. One of these questions is how the recycling process affects fiber characteristics. This thesis will deal specifically with this question.

"Controlled Overdrying: Effects On Some Physical Properties Of Fine Paper", John T. Collins

Paper Engineering Senior Theses

The purpose of this study was to determine the effects of certain drying variables on some physical strength properties when these variables were controlled to bring about overdrying conditions. The variables under study were contact time on the dryer can (% moisture) and different percentage hardwood-softwood compositions. From the study it was discovered that overdrying actually increases tensile values but mullen and tear values did indeed decrease.

The object of the following report was to see if there was a decrease, if any, in certain physical properties and to what degree. If overdrying a sheet actually decreases the physical properties …

Effect Of Glyoxylate On The Sensitivity Of Net Photosynthesis To Oxygen (The Warburg Effect) In Tobacco, David J. Oliver

David J. Oliver

The addition of glyoxylate to tobacco (Nicotiana tabacum) leaf discs inhibited glycolate synthesis and photorespiration and increased net photosynthetic 14CO2 fixation. This inhibition of photorespiration was investigated further by studying the effect of glyoxylate on the stimulation of photosynthesis that occurs when the atmospheric O2 level was decreased from 21 to 3% (the Warburg effect). The Warburg effect is usually ascribed to the increased glycolate synthesis and metabolism that occurs at higher O2 concentrations. Photosynthesis in control discs increased from 59.1 to 94.7 micromoles of CO2 per gram fresh weight per hour (a 60% increase) when the O2 level was …

The Effect Of Pigments In The Flotation De-Inking Of Newsprint, Harold M. Cody

Paper Engineering Senior Theses

This study was performed to determine the effect of the addition of pigments in the flotation de-inking of newsprint. It has been proposed that pigments aid in the flotation and removal of ink. Two pigments were investigated: talc and diatomaceous earth.

The addition of talc caused the brightness of the sheets to drop because the talc became heavily concentrated with ink. The addition of diatomaceous earth to the cell had no effect upon the flotation and removal of the ink. Therefore the addition of pigments to improve ink flotation and removal cannot be justified.

The Ornithogeography Of The Great Plains States, Paul A. Johnsgard

Paul Johnsgard Collection

It has long been recognized that the Great Plains represent a major transition zone in the distribution patterns of North American birds; field guides traditionally have treated the 100° W. longitude meridian as a convenient dividing line between eastern and western faunas. Furthermore, this line rather neatly bisects the political subdivisions of the Great Plains, namely the "plains states" extending from North Dakota southward through South Dakota, Nebraska, Oklahoma, and Texas. Of these, Texas is the least typical, its climate and fauna is strongly influenced by the Gulf Coast on the east and the Chihuahuan desert on the west. As …

Seizures And Brain Tumor In Neurologically Intact Adult Patients: Role Of Computerized Tomography (Ct Scan), Jamshid Seifi, Roushdy S. Boulos, Robert D. Teasdall

Henry Ford Hospital Medical Journal

CT scan of 13 patients with adult onset of seizures who were neurologically intact and otherwise asymptomatic revealed a supratentorial mass in all. Significant EEG abnormalities were recorded in five, and the isotope brain scan was positive in eight. In three patients, both studies were normal. Angiograms confirmed the location of tumor, and histology was established following craniotomy. The value of the CT scan as a screening test for detecting brain tumor in this group of seizure patients is evident.

In Vitro And Clinical Studies Of Cefaclor, A New Cephalosporin, Daria Kiani, Tom Madhavan, Keith Burch, Don Pohlod, Evelyn Fisher, Edward L. Quinn

Henry Ford Hospital Medical Journal

In vitro susceptibility studies of 246 clinical isolates demonstrated that this antibiotic was effective against Group A beta hemolytic streptococci, alpha hemolytic streptococci, S. pneumoniae, both penicillinase producing and nonpenicillinase producing Staphylococci, Klebsiella pneumoniae, and Proteus mirabilis. Cephalothin susceptible E. coii were also susceptible to cefaclor. Pseudomonas aeruginosa, Serratia sp., Enterobacter Sp., and Streptococcus faecalis were uniformly resistant to cefaclor. The efficacy and safety of this antibiotic were studied in 27 patients with urinary tract, soft tissue, and respiratory infections. Patients with urinary tract infections became abacteriuric after 48 hours. Patients with soft tissue infections responded well within the first …

Endoscopic Retrograde Cholangiopancreatography At Henry Ford Hospital: 1972-1977, Bernard M. Schuman, Kian H. Wong, R. Salimi, A. N. Adham

Henry Ford Hospital Medical Journal

Between 7972 and /977, 440 patients underwent endoscopic retrograde cholangiopancreatography (FRCP) at Henry Ford Hospital. The procedure was found to be most useful for identifying the site and nature of an extrahepatic obstruction, the diagnosis of pancreatic cancer, and the preoperative evaluation of chronic pancreatitis. One death occurred as a result of cholangitis in a patient with cancer of the pancreas. Review of the data has led us to refine our indications for FRCP. It has been shown to be a valuable technique with a low incidence of complications in evaluating pancreaticobiliary disease. Based on our study, it would be …

An Ischemic Infarct In Medulla And Cervical Cord, Ezzatollah Shivapour, Gilbert B. Solitare

Henry Ford Hospital Medical Journal

This report documents an unusual case of an occlusion of the anterior spinal artery of the medulla oblongata. The patient presented with involvement of the left accessory nerve and weakness of ipsilateral extremities. The diagnosis of an ischemic infarct in the distribution of the left proximal portion of the anterior spinal artery was made. Bulbar weakness, quadriplegia, and respiratory arrest developed. Postmortem examination, 23 days after onset, revealed an old infarct in the medulla which appeared as a more recent hemorrhagic infarct throughout the cervical cord.

Mixed Connective Tissue Disease And Systemic Lupus Erythematosus In One Family, Michael R. Lubetsky, Howard Duncan

Henry Ford Hospital Medical Journal

A mother with mixed connective tissue disease (MCTD) and a daughter with systemic lupus erythematosus (SLE) were simultaneously diagnosed and treated in August, 1977. Multiple cases of SLE occurring in the same family are not rare, but the frequency with which systemic lupus erythematosus and mixed connective tissue disease occurs in the same family is not known, and the reports are few. This report describes these two cases and suggests that mixed connective tissue disease may be part of the spectrum of systemic lupus erythematosus.

Caloric Restriction And Bile Salt Dynamics In Intact And Cholecystectomized Syrian Hamsters, J. Sanfield, W. T. Beher, G. J. Lin, R. Haamen

Henry Ford Hospital Medical Journal

In vivo studies of bile salt absorption and distribution using 14C-taurocholate were made in fed and fasted, intact and cholecystectomized Syrian hamsters. There was no significant difference in the rate of ileal 14C-bile salt absorption or the distribution of 14C-bile salts among the compartments of the enterohepatic circulatory system in any of the animals. The results showed that the sphincter of Oddi is patent in fasting, intact and cholecystectomized hamsters. They also suggested that the diminished bile salt pool seen in fasted, cholecystectomized but not in intact hamsters arises from a) a primary, fasting-induced decrease in liver enzyme activity involved …

Expanded Polytetrafluoroethylene (Ptfe) And External Velour Grafts As Small Artery Substitutes In Dogs, Farouq Samhouri, Luis H. Toledo-Pereyra, Stanley G. Dienst, Roger F. Smith

Henry Ford Hospital Medical Journal

This experimental study compared the clinical patency, angiographic appearance, and histology of 4 mm polytetrafluoroethylene (PTFE) and external double velour grafts which were used as external iliac artery substitutes in dogs. At one week there were no significant differences. However, at two months, none of the PTFE grafts were open, whereas six of the seven external double velour grafts were patent (p<0.05). Thus, in this study the 4 mm PTFE grafts are poor substitutes for canine iliac replacement.

Bone Erosion In Rheumatoid Arthritis, Howard Duncan, Catharina H. E. Mathews, Michael M. Crouch, A. M. Parfitt

Henry Ford Hospital Medical Journal

A histological study of fully mineralized bone sections was made on thirty joints surgically removed from patients with rheumatoid arthritis. The patterns of bone erosion fell into three groups: 1) that due to multinucleated osteoclasts; 2) areas of apparent bone erosion occupied exclusively by mononuclear cells; and 3) changes produced by an osteocyte which could either enlarge the lacuna space in which it resided or demineralize a region of bone in its immediate vicinity. Tissues taken from knee and hip specimens frequently showed all three cellular patterns of bone erosion, while the sections from finger joints rarely container multinucleated osteoclasts …
