Inorganic Nitrogen Determined By Laboratory And Field Extractions Of Two Forest Soils, H. Van Miegroet

Watershed Sciences Faculty Publications

To assess the effect of a delay in soil processing on inorganic N levels in N-rich soils, field and laboratory extractions were compared at two forested sites with high N mineralization and nitrification potential. At eight sampling dates in 1989 and 1990, five mineral soil cores per site were taken between 0- and 10-cm depth and transported on ice to the laboratory for KCl extraction and NH4-N and NO3-N analysis. At three sampling dates in 1990, soil extractions were performed in the field immediately following sampling, and inorganic N concentrations were compared between extractions. Nitrate-N increased four- to sevenfold (net …

Acidic Deposition, Ecosystem Processes, And Nitrogen Saturation In A High Elevation Southern Appalachian Watershed, C. S. Nodvin, H. Van Miegroet, S. E. Lindberg, N. S. Nicholas, D. W. Johnson

Watershed Sciences Faculty Publications

High-elevation red spruce-Fraser fir forests in the Southern Appalachian mountains: 1) receive among the highest rates of atmospheric deposition measured in North America, 2) contain old-growth forests, 3) have shown declines in forest health, 4) have sustained high insect-caused fir mortality, and 5) contain poorly buffered soils and stream systems. High rates of nitrogen and sulphur deposition (sim1900 and sim2200 Eq·ha–1·yr–1, respectively) are dominated by dry and cloud deposition processes. Large leaching fluxes of nitrate-nitrogen (100–1400 Eq·ha–1·yr–1) occur within the soil profile. We have expanded the study to the watershed scale with monitoring of: precipitation, throughfall, stream hydrology, and stream …

New Applications Of The Nuclear Microprobe For Biological Samples, Jan Pallon, Klas Malmqvist

Scanning Microscopy

The continuing development of the Nuclear Microprobe (NMP) has opened up new fields of applications in biology and medicine. Quantitative multielemental analysis in small sections of samples can be performed routinely. The use of techniques such as scanning transmission ion microscopy makes imaging as well as mass normalization possible at submicron resolution. Recent medical applications include studies on thin cryosections prepared from autopsies and biopsies, as well as single cells grown directly on the backing foil used in the NMP analyses. The purpose of the single cell analysis is often pharmacological, e.g., testing of new drugs, their uptake and distribution. …

Investigation Of Touch-Sensitive Responses By Hyphae Of The Human Pathogenic Fungus Candida Albicans, N. A. R. Gow, T. H. S. Perera, J. Sherwood-Higham, G. W. Gooday, D. W. Gregory, D. Marshall

Scanning Microscopy

Candida albicans is a fungus that commonly infects the mucosal surface of humans. The hyphal growth form of this fungus may initiate the primary invasion of the host. Here we show that hyphae respond thigmotropically and morphologically to cues such as the presence of a surface, pores, grooves and ridges. Growth on some firm surfaces elicits a helical growth response. Hyphae follow grooves and ridges of inert substrates and penetrate pores of filtration membranes. Our in vitro experiments suggest that thigmotropism may enhance the ability of a hypha to invade epithelia of a host at sites of weakened integrity.

Proceedings From The 31st Annual Italian And Specialty Cheese Seminar, Various Authors

Cheese Industry Conference

The impact of mixer temperature and mixer screw speeds on fat recovery, protein recovery, and yield of Mozzarella cheese was determined. In the first trial three different cheese temperatures were achieved: 130·F (54.C); 140•F (60.C); and 150.F (66·q. In the mixer temperature trial, a screw speed of 12 rpm (revolutions per minute) was used at all mixer temperatures. In the second trial, three different mixer screw speeds were used for stretching: 5 rpm, slow; 12 rpm, medium (ca. 50o/o of mixer full speed); 19 rpm, fast. Three vats of cheese were made per day. The two trials were conducted at …

Urinary Citrate, Bone Resorption And Intestinal Alkali Absorption In Stone Formers With Fasting Hypercalciuria, Piergiorgio Messa, Giuseppe Mioni, L. Paganin, A. Cruciatti, P. Lo Greco, D. Turrin

Scanning Microscopy

Reduced citrate in urine and increased fasting excretion of calcium are abnormalities frequently reported in stone forming (SF) patients. Increased dietary acid (or reduced alkali) introduction or absorption may be a potential cause of both these pathological findings. To test this hypothesis, we studied 64 SF patients {32 with fasting hypercalciuria (FH) and 32 without FH (NFH)}. After a basal evaluation for nephrolithiasis, while on a 500 mg calcium diet, they were evaluated for: (1) daily intestinal alkali absorption (IAA), by urinary electrolyte excretion; (2) basal concentrations of PTH, calcitonin (CT) and 1,25(OH)2-VitD; (3) oral calcium load for evaluation of …

Perennial Lymegrass (Leymus Arenarius And L. Mollis) As Potential Crop Species For Northern Latitudes, Kesara Anamthawat-Jónsson, Jón Gudmundsson, Birkir Bragason, P. K. Martin, R. M. D. Koebner

Herbarium Publications

The aim of the present study is to improve the perennial lymegrass (L. arenarius and L. mollis) for cultivation as potential cereal crop for Iceland as well as for other regions of native lymegrass distribution. The study will also provide cereal breeders with broader genetic resource containing several characters of the wild species such as tolerance to extreme environments and perhaps resistance to pathological diseases.

Evaluation And Utilization Of Biodiversity In Triticeae For Wheat Lmprovement, A. B. Damania, J. Valkoun

Herbarium Publications

To adapt new varieties to a wide spectrum of environments breeders and farmers have emphasized the need for broadening the current narrow genetic base of modern varieties of important cereal crops such as wheat and barley. In response to this need, several thousand samples of indigenously cultivated Triticeae species and their wild relatives have been collected from the centers of diversity. However, gene bank collections are of little use if they are not evaluated and the information disseminated widely. Evaluation is essentially the link between conservation and use. Some of the collected material has been evaluated at the International Center …

Genomes, Chromosomes, And Genes And The Concept Of Homology, Gitte Petersen, Ole Seberg

Herbarium Publications

The traditional application of genome analysis in phylogenetic inference is questionable. Hypotheses about phylogeny are based upon the analysis of homologous characters, existing as a consequence of common descent. The concept of homology in morphology and molecular biology is well-defined: To count as an homology any character must pass the similarity, congruence, and conjunction tests. In genome analysis homology is related to the behaviour of chromosomes during meiosis: homologous chromosomes pair, nonhomologous chromosomes do not. Thus, in genome analysis homology becomes a purely operational concept. How well does this operational concept work? And what are the relationships, if any, between …

Physical Mapping Of Micronutritional Genes In Wheat-Rye Translocations, R. G. Kynast, M. S. Röder, V. Römheld

Herbarium Publications

In rye (Secale cereale L.), there are loci on chromosome arm 5RL which give rise to increased copper (Cu)- and iron (Fe)-efficiency, respectively. Four different wheat-rye translocations each harboring a terminal segment of different size of the rye chromosome arm 5RL were identified by test crosses and Giemsa-banding: 'T29' (5AS.5RL), 'T63' (5BS.5BL-5RL), 'Vhn' (4BS.4BL-5RL) and 'Cor' (4BS.4BL-5RL). The translocation break points were detected by chromosome painting technique GISH and the sizes of the rye chromosome segments involved were determined by computer image analysis. The Cu-efficiency gene Ce was physically mapped to the terminal region of 5RL, and the genes …

Diversity Of Trypsin Inhibitors In Cultural And Wild Barley, Ladogina M. P., Ovchinnikov A. N., Fetisov A. V.

Herbarium Publications

Diversity of trypsin inhibitors was studied in 35 spring barley cultivars (Hordeum vulgare), 21 samples of H. spontaneum, and 3 samples of H. agriocrithon. Six variants of trypsin inhibitor spectra were identified by native electrophoresis method followed by specific development of activity. Four variants were found in both cultivated and wild barley, and the other two were revealed only in H. spontaneum. Trypsin inhibitor activities (TIA) and soluble protein contents were determined in four cultivars with different variants of trypsin inhibitors. It was shown that TIA differed in the cultivars studied and did not correlate …

Plant Germplasm Resources, S. A. Eberhart, H. E. Bockelman

Herbarium Publications

Landraces and wild relatives of crops from centers of diversity have been rich sources of resistance to new pathogens, insect pests, and other stresses as well as for traits to improve food and fiber quality, animal feed, and industrial products. Because very few crops grown in the U.S. are native, plant introductions are vital to our agriculture. The National Plant Germplasm System (NPGS) was established to acquire, preserve, and distribute plant genetic resources from around the world so that scientists have immediate access to these source materials. The active collection is maintained and distributed by 19 national germplasm repositories. The …

Effect Of Irrigation On Crabapple Growth And Water Relations During Field Production With In-Ground Fabric Containers, Roger Kjelgren, C. Spihlman, B. R. Cleveland

Plants, Soils, and Climate Faculty Publications

Growth and water relations of irrigated and non-irrigated Malus sieboldii var. zumi produced with and without in-ground fabric containers in a field-nursery setting were investigated. Predawn and midday leaf water potential and midday stomatal conductance were measured periodically through the season, and trunk increment, leaf area, root growth, and osmotic potential were measured in late season. Water potential became more negative and stomatal conductance decreased in non-irrigated treatments during an extended mid-summer drought that resulted in less trunk diameter gorwth and leaf area. Trees grwon in fabric-containers, both irrigated and non-irrigated, exhibited no detectable differences in water relations over the …

Interactions Of Harvester Ants And Seeds In A Sagebrush-Steppe Ecosystem: The Effect Of Trunk Trail Foraging, John F. Mull

Biology

The primary goal of this study was to document spatial variation in the interactions between a granivore, the western harvester ant (Pogonomyrmex occidentalis), and its seed resources in the semiarid sagebrush-steppe of southwestern Wyoming. A major focus of this research was the effect of foraging trail use by P. occidentalis on spatial patterns of seed predation. Three seed removal experiments, soil seed sampling and an experiment designed to test the role of visual landmarks on foraging trail formation were the major elements of this investigation. In the first two seed experiments, seed removal rates, from both high- and …

Consumption Of Iron-Fortified Cheese And Lipid Peroxidation In Females, Gene Joseph Giunti

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dairy products are important sources of calcium and other nutrients but are a poor source of dietary iron. Cheese comprises a substantial portion of dairy food consumption and has been determined an appropriate medium for iron-fortification. However, iron may promote the potentially harmful process in food and biological systems known as lipid peroxidation. Therefore, the safety of consuming iron-fortified cheese was examined.

Commercial-scale batches of Cheddar cheese were iron-fortified to a level of two milligrams of iron per ounce with either ferric chloride, ferric-casein complex, or ferric-whey protein complex. Fifty-four premenopausal females were divided into three treatment groups and supplemented …

Officially Reported Characteristics Of Spouse Abuse Victims Seeking Assistance In Utah, 1992, Kevin D. Thompson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Spouse abuse is a significant social problem that has recently received considerable attention by family researchers. National studies have estimated the incidence of spouse abuse in the United States, but few studies have been conducted at the state or local level.

Data were obtained from the Utah Division of Family Services Domestic Violence Client Record (Form 741-S) reporting system. A total of 1,363 primary victims of spouse abuse was identified for the calendar year 1992.

It is posited that victims of low socioeconomic status and victims of severe physical abuse are more likely to return to their own home after …

Transcervical Versus Laparoscopic Insemination In Nulliparous And Multiparous Ewes After Estradiol Cypionate Treatment, Tami L. Gage

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The only practical method for artificially breeding ewes with frozen semen is laparoscopic insemination into the lumen of the uterine horn. Like all surgical procedures, however, laparoscopic artificial inseminatiom has limitations. The procedure requires surgical skill and costly equipment. Repeated passage of the laparoscope through the abdominal wall causes adhesions. Depositing frozen/thawed semen at the os cervix results in low conception rates. The inability to pass an insemination pipette through the cervix has prevented artificial insemination in sheep from becoming a standard breeding method as in the cattle industry. This study compared laparoscopic and transcervical methods of insemination in nulliparous …

Molecular Toxicology Of Pyrrolizidine Alkaloids, Hea-Young Kim

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pyrrolizidine alkaloids are cytotoxic, carcinogenic, and anti-carcinogenic in vivo and in vitro, and they produce many hazardous effects in humans and animals. Pyrrolizidine alkaloids (PAs) also cross-link with DNA and/or protein. However, whether such cross-linking is important to the toxic action of PAs is not known. In addition, the exact mechanism underlying these DNA cross-links or cytotoxicity is also not clear.

In three separate studies, I characterized the nature of PA-induced DNA cross-links and the relationships between PA structures and cross-linking potency. In the first study (Chapter II), I found that cross-linking potency of PA congeners coincided with their …
