Determination Of Dimethylselenide And Dimethyldiselenide By Gas Chromatography–Photoionization Detection, William J. Hunter, L. David Kuykendall Jan 2004

Determination Of Dimethylselenide And Dimethyldiselenide By Gas Chromatography–Photoionization Detection, William J. Hunter, L. David Kuykendall

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

A simple method for the determination of volatile selenium compounds employing a gas chromatograph equipped with a photoionization detector is described. The method involves the direct injection of dimethylselenide (DMS) or dimethyldiselenide (DMDS) into the gas chromatograph; no derivatization of the sample was required. The photoionization detector was capable of detecting 60 pg (0.55 pmol) of DMS and 150 pg (0.80 pmol) DMDS. Sensitivity was 10–50 times greater with DMS and 4–20 times greater with DMDS when the photoionization detector was employed than when the flame ionization detector was employed.

Detection And Characterization Of Amitraz Resistance In The Southern Cattle Tick, Boophilus Microplus (Acari: Ixodidae), Andrew Y. Li, Ronald B. Davey, Robert J. Miller, John E. George

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Amitraz, a formamidine acaricide, plays an important role in the control of the southern cattle tick, Boophilus microplus (Canestrini), and other tick species that infest cattle, dogs, and wild animals. Although resistance to amitraz in B. microplus was previously reported in several countries, the actual measurement of the level of amitraz resistance in ticks has been difficult to determine due to the lack of a proper bioassay technique. We conducted a survey, by using a newly reported technique that was a modification of the standard Food and Agriculture Organization larval packet test, to measure the levels of resistance to amitraz …

Temperature-Dependent Oxygen Limitation In Insect Eggs, H. Arthur Woods, Ryan I. Hill Jan 2004

Temperature-Dependent Oxygen Limitation In Insect Eggs, H. Arthur Woods, Ryan I. Hill

College of the Pacific Faculty Articles

Most terrestrial insect embryos support metabolism with oxygen from the environment by diffusion across the eggshell. Because metabolism is more temperature sensitive than diffusion, embryos should be relatively oxygen-limited at high temperatures. We tested whether survival, development time and metabolism of eggs of a moth, Manduca sexta, were sensitive to experimentally imposed variation in atmospheric oxygen availability (5–50 kPa; normoxia at sea level is 21 kPa) across a range of biologically realistic temperatures. Temperature–oxygen interactions were apparent in most experiments. Hypoxia affected survival more strongly at warmer temperatures. Metabolic rates, measured as rates of CO2 emission, were virtually insensitive …

Student Works (2000-2009)

Expert Systems are computer programs that use artificial intelligence to solve problems within a specialized domain that ordinarily requires human expertise. A very important aspect of helping mycologist with diagnosis of the mushroom health effects is the identification itself by using only the visible feature of the mushroom. Their identification, although very important, is often difficult. This thesis addresses this problem by providing an expert system that takes into consideration various factors about the mushroom, and presents identification as a possible solution. In order to achieve the purpose, the system uses Prolog, a logic programming. In this paper, chapter one …

The pulse-coupled neuron, which is significantly-different from the conventional artificial neuron, is a result of recent research conducted on the visual cortex of cats and monkeys. Pulse-coupled neural networks (PCNNs) are modeled to capture the essence of recent understanding of image interpretation processes in biological neural systems. Study indicates that the PCNN is capable of image smoothing, image segmentation and feature extraction. The PCNN reduces noise in digital images better than traditional smoothing techniques. As an image segmented the PCNN performs well even when the intensity varies significantly within regions, and adjacent regions have overlapping intensity ranges.

Student Works (2000-2009)

The traditional learning method, lecture-based learning that's still dominating learning method not only Malaysia, but almost everywhere in the world, can no longer ensure student's career stability in real world after education despite high academic achievement. In lecture-based learning or LBL, students usually tend to memorize information that the teachers feed to them for examination purpose without really understanding the meaning of the facts. This scenario won't guarantee students' readiness to face real problems in real world, a they won't be able to apply their knowledge in a more real-life context. Problem-based learning (PBL) however encourages students to learn how …

Loline Alkaloid Biosynthesis In Neotyphodium Uncinatum, A Fungal Endophyte Of Lolium Pratense, Jimmy Douglas Blankenship Jan 2004

Loline Alkaloid Biosynthesis In Neotyphodium Uncinatum, A Fungal Endophyte Of Lolium Pratense, Jimmy Douglas Blankenship

University of Kentucky Doctoral Dissertations

Some endophytes in mutualistic associations with Festuca, Lolium and other grass species produce insecticidal loline alkaloids (1-aminopyrrolizidines; LA). These loline alkaloids have a saturated pyrrolizidine ring system (two-rings sharing a carbon and nitrogen atom), a 1-amine substituted with methyl, acetyl, or formyl groups, and an oxygen bridge between C-2 and C-7. The development of a reliable system of production of LA in cultures of the Lolium pratense (meadow fescue) endophyte, Neotyphodium uncinatum, facilitated work on the LA biosynthetic pathway. N. uncinatum produced norloline, loline, methylloline, N-acetylnorloline (NANL), N-formylloline (NFL), and N-acetylloline as detected in culture filtrates. The total production …

Probabilistic Databases And Their Applications, Wenzhong Zhao Jan 2004

Probabilistic Databases And Their Applications, Wenzhong Zhao

University of Kentucky Doctoral Dissertations

Probabilistic reasoning in databases has been an active area of research during the last twodecades. However, the previously proposed database approaches, including the probabilistic relationalapproach and the probabilistic object approach, are not good fits for storing and managingdiverse probability distributions along with their auxiliary information.The work in this dissertation extends significantly the initial semistructured probabilistic databaseframework proposed by Dekhtyar, Goldsmith and Hawkes in [20]. We extend the formal SemistructuredProbabilistic Object (SPO) data model of [20]. Accordingly, we also extend the SemistructuredProbabilistic Algebra (SP-algebra), the query algebra proposed for the SPO model.Based on the extended framework, we have designed and implemented …

Maintenance Of Sexually Dimorphic Patterns Of Growth And Reproduction In Marchantia Inflexa, Linda Catherine Fuselier Jan 2004

Maintenance Of Sexually Dimorphic Patterns Of Growth And Reproduction In Marchantia Inflexa, Linda Catherine Fuselier

University of Kentucky Doctoral Dissertations

Sexual dimorphism in life history traits may influence the distribution of the sexes,population sex ratios, the maintenance of sex in populations, and the evolutionarypotential of a species. In bryophytes, sexual dimorphism in traits related to growth andreproduction may be responsible for female-biased population sex ratios and a lack ofsexual reproduction. I examined the roles of natural selection in maintaining sexualdimorphism in the context of impacts on bryophyte population sex ratios, usingMarchantia inflexa as a model system. My studies included an assessment of amongpopulationvariation in habitat use by the sexes, comparison of phenotypes betweensingle-sex and both-sex populations, a field study of …
