Hatching Of Sod Webworm Eggs In Relation To Low Temperatures, E. A. Heinrichs, Ellis L. Matheny

Department of Entomology: Faculty Publications

Eggs of Chrysoteuchia topiaria (Zeller), Crambus pascuellus floridus (Zeller), and Pediasia trisecta (Walker) were exposed to temperatures of 25, 15, 10, 4, and –10°C. Only those of P. trisecta hatched after exposure to 4°C for 30 days, while none hatched after exposure to –10°C. Eggs of none of the species hatched after exposure to 4 and 10°C for 60 days. Pre-exposure and post-exposure conditioning had no significant effect on percent hatch of P. trisecta eggs, while length of exposure period had a significant effect.

Lipid Content And Seasonal Activity Of Odontopus Calceatus (Coleoptera: Curculionidae) Adults, E. A. Heinrichs

Department of Entomology: Faculty Publications

Overwintering Odontopus calceatus (Say) adults were first observed feeding on April 10. Weekly collections during the activity period indicated that new-generation adults began emerging June 4. By July 23 they had entered the forest litter for hibernation. Lipid content decreased throughout the hibernation period as the weevils utilized 77% of their total lipid content during this time. The most rapid decrease during hibernation occurred from February to March, just prior to mating and oviposition in the spring. No increase in lipid content occurred during the activity period in spring and summer. A great increase in lipid content did occur within …

The Effect Of Nitrogen Rate And Method Of Sucker Control On Dry Matter Accumulation In Different Plant Parts Of Burley 21 Tobacco, J. L. Sims, W. O. Atkinson

Agronomy Notes

Earlier research has shown that higher leaf yields of burley tobacco result from topping and controlling sucker (axillary bud) growth. Suckering practices which provide the greatest degree of sucker control generally result in highest leaf yields . Chemically suckering with maleic hydrazide (MH-30) and other chemicals provides for a higher degree of control than most hand sucker ing practices although hand sucker ing at frequent intervals may produce leaf yields comparable to those from use of maleic hydrazide. High leaf yields resulting from a high degree of sucker control has been attributed to the elimination of the use of photosynthate …

Strength Properties Of Secondary Fibers Repulped Under Various Conditions, David J. Deyoung

Paper Engineering Senior Theses

The inability of fibers to swell to their original extent is probably the largest single factor contributing to strength losses of repulped fibers. This lack of swelling lessens the number and strength of fiber to fiber bonds in the sheet formed. It is this fact which leads to the decreased mullen, tensile and stretch of the sheet, and the increased tearing resistance. This paper is a study of the effects of temperature, pH and surfactants on the strength properties of secondary fibers. It was shown that a surfactant is very detrimental to strength properties. While not affecting some strength properties, …

The Prevalence Rate Of Congenital Heart Disease In Newborn Gerbils (Meriones Unguiculatus): A Preliminary Report, Jami G. Shakibi, Lester Weiss

Henry Ford Hospital Medical Journal

A preliminary report on the prevalence rate of congenital heart disease in newborn gerbils (Meriones unguiculatus) is presented. Serial sections of the entire heart of 100 liveborn gerbils were studied. The prevalence rate of congenital heart disease was 4%. Ventricular septal defect was the most frequent lesion. This is in agreement with previous reports on rats.

Evaluation Of Cellular-Level Haversian Bone Resorption In Human Hyperparathyroid States: A Preliminary Report, H. M. Frost, A. R. Villanueva, Z. F. Jaworski, P. Meunier, A. G. Shimizu

Henry Ford Hospital Medical Journal

Cellular-level bone resorption was evaluated in 16 patients undergoing renal dialysis and in two with primary hyperparathyroidism, by quantitative histological means using tissue time markers. When averaged over periods greater than two weeks, the individual osteoclasts in these patients resorbed less bone in unit time than normal.

Photographic Features Of Benign And Malignant Ulcers, N. V. Carandang, B. M. Schuman, R. J. Priest

Henry Ford Hospital Medical Journal

One hundred and twenty-nine cases of benign gastric ulcer and 17 cases of malignant gastric ulcer studied by intragastric photography are reviewed. The benign ulcer, characterized by symmetrical contour and smooth base, was diagnosed correctly on the initial photographic study in 97.7% of cases. Malignant ulcers were diagnosed correctly in 59% of cases on the first study. The importance of color photography to complement roentgenographic evaluation of gastric ulceration is emphasized.

The Mechanism Of Formation Of Certain Ventricular Septal Defects: A New Hypothesis, Jami G. Shakibi, Lester Weiss

Henry Ford Hospital Medical Journal

The generally accepted and most common mechanism of the pathogenesis of VSD is the failure of fusion of the conus ridges, atrioventricular cushions and the ventricular muscular septum. Our findings in a study of serial sections of the hearts of newborn gerbils (Meriones unguiculatus) leads us to hypothesize a second, less common, mechanism for the development of VSD, i.e., an exaggeration of the normal process of resorption and atrophy which undermines the septal cusp of the tricuspid valve, thus separating it from the muscular septum. This hypothesis can explain an instance of high membranous VSD in the form of a …

Cation Transport I. Metabolic Activity Of The Polyphosphoinositide Complex In Isolated Renal Cortex Tubules, Paul Bartlett, James F. Bossart

Henry Ford Hospital Medical Journal

Although several mechanisms have been proposed to explain the transport of hydrophylilc cations across lipoprotein barriers, the nature and identity of the carrier mechanism have not yet been elucidated. The present communication is concerned with a mechanism postulating that monoesterified phosphate on the inositol moiety of phosphatidyl inositol might provide anionic sites that function as cation carriers via a phosphorylation-dephosphorylation cycle, catalyzed in its simplest sequence by phosphatidyl inositol kinase and diphosphoinositide phosphomonoesterase activities. In this context, one might reasonably expect that turnover of monoesterified phosphate in the polyphosphoinositides of isolated renal cortex tubules would be reduced in tubules in …

Pneumatosis Cystoides Intestinalis: The Report Of A Case Associated With Severe Pulmonary Disease And Chronic Lymphocytic Leukemia, Russell J. Crider, Philip Bentlif

Henry Ford Hospital Medical Journal

Pneumatosis cystoides intestinalis is discussed with emphasis on its clinical, radiologic, sigmoidoscopic, surgical and pathological characteristics. The four theories of the etiology of P.Cl. are neoplastic, infectious, nutritional, and mechanical. These theories are discussed, and a case of P.C.I, associated with severe pulmonary disease and chronic lymphocytic leukemia is presented to lend support to the mechanical theory.

Alcaptonuria And Ochronosis With Diabetes Mellitus And Mycosis Fungoides: A Case Report, Jamshed U. Haq, Roy B. Patton

Henry Ford Hospital Medical Journal

A Negro woman with alcaptonuria, ochronosis, ochronotic arthropathy, diabetes mellitus and mycosis fungoides died of acute renal failure due to diabetic glomerulonephropathy and ochronotic nephrosis. The role of the renal lesions of ochronosis is presented in potentiating the effect of an underlying renal disease producing rapidly progressive kidney failure. The occurrence of ochronosis, diabetes mellitus and mycosis fungoides is apparently coincidental only. Special stains of tissue sections confirm the similarity of melanin and ochronotlc pigment.

Promethazine-Chlorpromazine Combination In The Treatment Of Unmanageable Psychotic Patients, Armando R. Favazza

Henry Ford Hospital Medical Journal

Administering a combination of promethazine and chlorpromazine to patients with a "galloping psychosis" has an antipsychotic and tranquilizing effect which calms them down to a more manageable and less aggressive state. The drugs are chemically similar; promethazine's actions are strongly potentiated in the combination, so large doses must be given under careful supervision. Case histories demonstrate successful short term management of acutely psychotic, aggressive patients who were a danger to themselves and others.

Protein Synthesis During Fungal Spore Germination. Iv. Transfer Ribonucleic Acid From Germinated And Ungerminated Spores, James L. Van Etten, R. Kent Koski, Mahmoud El-Olemy

Department of Plant Pathology: Faculty Publications

Transfer ribonucleic acid (tRNA) fractions isolated from germinated and ungerminated spores of Botryodiplodia theobromae and Rhizopus stolonifer had acceptor activity for all 20 amino acids commonly found in protein, when tested with an enzyme fraction from germinated spores. Accordingly, it is unlikely that the absence of tRNA for a particular amino acid limits protein synthesis in fungal spores.

Parasitic Organisms In The Blood Of Arvicoline Rodents In Alaska, Francis H. Fay, Robert L. Rausch

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

A Grahamella-like organism (Schizomycetes: Bartonellaceae) was found in erythrocytes of laboratory-reared northern voles, Microtus oeconomus Pallas, which had been inoculated intraperitoneally with a saline suspension of ground fleas, Megabothris abantis (Roths.), from wild northern voles captured at Lower Ugashik Lake, Alaska Peninsula. A live-trapped northern vole from the same locality harbored trypanosomes referable to T. microti (Mastigasida: Trypanosomatidae). Two morphologically similar but biologically different strains of piroplasms (Piroplasmasida: Theileriidae) of uncertain generic status were isolated from northern voles of Ugashik Lake origin and from northern red-backed voles, Clethrionomys rutilus Pallas, from the vicinity of Anchorage, Alaska. In the natural …

Sweetclover Weevil Feeding Stimulants: Isolation And Identification Of Glucose, Fructose, And Sucrose, W. R. Akeson, H. J. Gorz, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

The water-soluble fraction of Melilotus leaves previously referred to as Stimulant A was further fractionated by preparative paper chromatography into three factors, each having a stimulatory effect on sweetclover weevil feeding. The three factors, designated Stimulant A₁, A₂, and A₃, were identified as sucrose, glucose, and fructose, respectively, by co-chromatography with known sugars on cellulose-coated thin-layer plates. Silver nitrate, anisidine phthalate, and anthrone were employed as detection agents. The isolated compounds and corresponding reagent grade sugars were identical in chromatographic and chemical behavior, as well as in feeding stimulant activity. Sucrose stimulated the greatest …

Environmental Modification Of Bluegill (Lepomis Macrochirus Rafinesque) In Chilhowee, Loudon, And Norris Reservoirs, Tennessee, Edward Bartlett Smythe Ii

Masters Theses

This thesis reports the results of an investigation of environmental modifications of bluegill (Lepomis macrochirus Rafinesque) in Chilhowee, Loudon, and Norris Reservoirs. The three reservoirs are located in the Tennessee River drainage system.

The investigation was carried out between the spring of 1968 and the fall of 1969. Collecting was done by angling using both natural and artificial bait.

The evidence obtained by the investigation indicated significant differences occurred in the meristic and morphometric characters of the three bluegill populations when the data was tested statistically. It is concluded that the differences detected were probably due to environmental forces, …

A Comparison Of Climatic Elements At Four Elevations In The Great Smoky Mountains National Park, Luther Allin Stephens Jr.

Masters Theses

Between January 1, 1947, and December 31, 1950, hourly temperature and relative humidity and daily precipitation and cloud cover data were collected at the 1,460 ft., 3,850 ft., 5,000 ft., and 6,300 ft. elevations in the Great Smoky Mountains National Park. These four years were part of a period of data collection extending from January, 1946, through March, 1951. These data were processed by a digital electronic computer, IBM 7040, under the control of data summary and potential evapotranspiration programs. Selected statistical tests were employed to compare the similarity of variation in some monthly mean values or to determine the …
