Cytotypes And Morphometrics Of Two Phyllostomatid Bats, Micronycteris Hirsuta And Vampyressa Pusilla, Robert J. Baker, Hugh H. Genoways, William J. Bleier, Jerry W. Warner

University of Nebraska State Museum: Mammalogy Papers

Jackson and Patton stated that the key to understanding mechanisms of chromosomal evolution lies in studies of chromosomal variation within populations that can hybridize. Hybrids between cytotypes contain the answer to problems of meiotic pairing and reduced fertility, as well as information concerning the nature of zones of contact. However, before detailed studies can be initiated, chromosomal races and hybrid zones must be located. Few chromosomal races have been described for bats. Within the family Vespertilionidae, five species are known to have such races and races have been reported in two species of the family Phyllostomatidae.

Described are chromosomal races …

University of Nebraska State Museum: Mammalogy Papers

As pointed out by Jackson (1971) and Patton (1972), the key to understanding mechanisms of chromosomal evolution lies in studies of chromosomal variation within populations that can hybridize. Hybrids between cytotypes contain the answer to problems of meiotic pairing and reduced fertility, as well as information concerning the nature of zones of contact. However, before detailed studies can be initiated, chromosomal races and hybrid zones must be located. Few chromosomal races have been described for bats (Baker, 1970a). Within the family Vespertilionidae, five species are known to have such races (Baker, 1970a) and races have been reported in two species …

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.

Protein-Phospholipid Interactions In Heated Phospholipid Emulsions Containing Bovine Myoglobin Or Sarcoplasmic Proteins, Sharon Lynn Melton

Doctoral Dissertations

A simplified procedure for determination of myoglobin concentration in aqueous muscle extract was developed. The procedure was used in an investigation of possible interactions between phospholipids and bovine myoglobin, either isolated or as a component of sarcoplasmic proteins. Investigation of the possible interactions was carried out as follows. Solutions containing myoglobin or sarcoplasmic proteins and emulsions (phospholipid, sarcoplasmic protein-phospholipid, and myoglobin-phospholipid) were heated from 25°C to end point temperatures up to 77°C. The following measurements were made on all protein dispersions; (1) pH; (2) percent protein remaining dispersed; (3) myoglobin concentration; (4) available lysine, basic group and acidic group equivalents …

Fluometuron And 2,4,5-T Residues In Soil, Sediment, Runoff Water, And Percolation Water, Glenn Gray Davis

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 residue amounts …

Tb65: The Commercial Use Of Puckerbrush Pulp, Andrew J. Chase, Fay Hyland, Harold E. Young

Technical Bulletins

This study investigates the potential of several local puckerbrush or weed trees and shrubs as sources of fiber for papermaking. Four different pulping processes were used (sulfate, magnesium bisulfite, neutral sulfite semichemical, and cold caustic) with six puckerbrush species (alder, gray birch, red maple, pin cherry, aspen, and willow). Mixtures of puckerbrush species, and commercial chip-puckerbrush species mixtures were pulped by the sulfate process with the objective of producing a pulp that would be suitable for fine-grade papers. The results produced a good grade of bleachable pulp with adequate physical characteristics for most fine paper grades. The other three pulping …

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 …

Effects Produced By Varying Types Of Drying On Starch Coated Paper Properties And Binder Migration, Mark J. Schaefer

Paper Engineering Senior Theses

The major concern of this report is binder migration and the factors which play a major role contributing to its presence. The major factors studied were coatings using varied drying methods, adhesive levels, % solids and types of starches.

Results obtained show that to obtain minimal migration coatings should be dried evenly throughout using infrared sources of heat.

Coating with different adhesive levels will vary optical and strength properties. Binder migration is more evident when using lower adhesive levels.

Coating at different % solids did not have any real significant effect in this study due to a very short span …

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 …

The Effectiveness Of Oxandrolone In Promoting Linear Growth In Growth Hormone Deficient Children, Charles B. Wolf, Raymond C. Mellinger, Lewis B. Morrow, M. Saeed-Uz Zafar

Henry Ford Hospital Medical Journal

This two-year study consisted of a comparison of oxandrolone and growth hormone for the treatment of five children with documented growth hormone deficiency. Previously, androgens have been reported to be relatively ineffective in accelerating linear growth In growth hormone deficient children. Oxandrolone was administered for one year. Growth hormone was added in the second six months and then was given as a single agent in the third six months. Growth accelerated markedly in all patients. Only one child showed more rapid growth with the addition of growth hormone while two children actually grew more rapidly under the Influence of oxandrolone …

Surgical Treatment Of Liver Trauma: Technical Considerations And Case Reports, C. Grodsinsky, T. A. Fox Jr., B. E. Brush

Henry Ford Hospital Medical Journal

The incidence of abdominal trauma, and thus that of liver trauma, has been increasing in the past few years. Improvements in the understanding of the anatomy of the liver and improvements in diagnostic techniques have resulted in shorter and better operations with less delay between injury and surgery. Improvements in transportation to adequate hospital facilities and vigorous resuscitative measures have also contributed to lowering the mortality rate for this type of injury. Suggestions are made for the surgical management of liver injuries, together with illustrative case reports.

Near Basal Blood Pressure: A Method Applicable To Clinical Practice, John R. Caldwell

Henry Ford Hospital Medical Journal

A method is described for determining near basal blood pressure (NBBP) measurements that is applicable to outpatient clinic or office use in daily practice. In our clinic, patients' mean casual pressure was significantly higher than the NBBP, the difference being 40 mm Hg systolic (p < .001) and 18 mm Hg diastolic (p < .001). In hospitalized patients the casual blood pressure was higher than the fourth to sixth day hospital average, and the hospital average was higher than NBBP. The difference between the last two was 15 mm Hg systolic (p <. 005) and 9 mm Hg diastolic (p < .005). In patients recording blood pressure readings at home the average weekly home-recorded blood pressure was not significantly different from NBBP during the same week, -1 mm Hg systolic (p > .80) and 4 mm Hg diastolic (p > .10). NBBP by this method offers a practical way to estimate the average daily blood pressure.

Electrical Alternans In Cardiac Tamponade, Andreas P. Niarchos

Henry Ford Hospital Medical Journal

Of nine patients with pericardial effusion due to various causes, four developed cardiac tamponade. Electrical alternans was present In all four, being total in three, and ventricular in one. From the diagnostic point of view, the alternans corresponded with the clinical diagnosis of cardiac tamponade and the radiological signs of a large pericardial effusion. The pericardial fluid was hemorrhagic in three patients and transudate (hydropericardium) in the fourth. In two patients alternans was present with heart rates below 100 per minute. Apart from the exact (1:1) type of electrical alternans, three new types are described; a 2:1, 3:1 and a …

Efficacy Of Betaprone With Ultraviolet Irradiation On Hepatitis B Antigen In Human Plasma Pools (A Retrospective Study), Gerald A. Logrippo, Hajime Hayashi

Henry Ford Hospital Medical Journal

In a retrospective study, hepatitis B antigen (HB Ag) was found in 14 lots of human plasma pools (16-20 liters each) that had been treated by the combined Betaprone (BPL) with ultraviolet (UV) irradiation procedure. No evidence of clinical hepatitis was found during a six-month follow-up after 185.2 liters of HB Ag positive plasma were Infused into 257 patients. Since HB Ag positive blood products treated by BPL with UV produced no clinical hepatitis, it is evident that our treatment is efficacious against hepatitis virus agents.

Seasonal Food Habits Of European Wild Hogs (Sus Scrofa) In The Great Smoky Mountains National Park, Charles D. Scott

Masters Theses

This study was conducted on the Tennessee side of the Great Smoky Mountains National Park from the fall of 1971 to the spring of 1973. Seasonal food habits information of the European wild hog (Sus scrofa) was obtained by the analyses of stomach contents.

Hogs ate primarily plant material in all seasons. Grasses (Gramineae) were the most important food item in the spring. Grasses were important to hogs in the summer, as were the fruits of Gaylussacia sp., Vaccinium sp., and Malus sp. Roots were the major food item in the fall and winter months, although the mast …

How Many Cranes Make A Skyful?, Paul A. Johnsgard

Paul Johnsgard Collection

Every year thousands of lesser sandhills congregate along the Platte River in Nebraska on their spring migration northwards. Mainly because of local damage caused by the birds during their fall migration, they have been legally hunted since 1961. Can the population survive such persistent destruction?

One may ask the question “How many cranes are enough?” This is perhaps analogous to the rhetorical question as to how many redwood trees are needed to make a viable forest; for a remnant crane population is not only unimpressive but also seemingly does not survive or reproduce well, judging from population trends in the …
