The Economic Effects Of Ski Resorts On Communities In The State Of Maine, Rachel Freierman

Undergraduate Research Symposium (UGRS)

Skiing and snowboarding is a fairly expensive activity for participant and one in which the industry as a whole makes handsome profits. In the 2005/06 season, resorts in the Northeast reported an average gross revenue of $18.5 million. (NSAA) With the current weather phenomenon of El Nino, however, resorts in New England especially, have been suffering economically. The gross revenue in New England in the ’05/’06 season was down 4% from the previous year, likely due to the fact the total snowfall declined by 16%. (NSAA) Much of this loss in revenue came during the Christmas to New Years vacation …

Determination Of Mrna Half-Lives In Candida Albicans Using Thiolutin As A Transcription Inhibitor, Bessie W. Kebaara, Lindsey E. Nielsen, Kenneth Nickerson, Audrey L. Atkin

Kenneth Nickerson Papers

A method for determining mRNA half-lives in the polymorphic fungus Candida albicans is described. It employs growth in a defined medium, the inhibition of transcription with thiolutin (10–20 μg/mL), and quantitative Northern blotting. The method is effective for the A72, SC5314, and CAI-4 strains of C. albicans, and for mRNAs that have a wide variety of decay rates and steady-state abundances. The range of half-lives detected (from 4–168 min) shows that this method is effective for mRNAs with widely varying half-lives. The mRNA decay rates obtained are compared with those for orthologous mRNAs from Saccharomyces cerevisiae. This procedure …

Authorship In Ecology: Attribution, Accountability, And Responsibility, Jake F. Weltzin, R. Travis Belote, Leigh T. Williams, Jason K. Keller, E. Cayenne Engel

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Quality and quantity of publications are among the most important measures determining the success of ecologists. The past 50 years have seen a steady rise in the number of researchers and collaborative manuscripts, and a corresponding increase in multi-authored articles. Despite these increases, there remains a shortage of useful and definitive guidelines to aid ecologists in addressing authorship issues, leading to a lack of consistency in what the term “author” really means. Deciding where to draw the line between those who have earned authorship and those who are more appropriately credited in the acknowledgments may be one of the more …

The Use Of Capillary Electrophoresis (Ce) In Drug Analysis, Agnes D. Garcia

FIU Electronic Theses and Dissertations

Capillary electrophoresis is currently a very powerful technique for the analysis of seized drugs. A rapid analytical CE method for the screening and quantification of GHB and GBL was achieved using 300mM CTAC/25mM phosphate buffer pH 6.3. Reversed phase HPLC was achieved using 25mM phosphate buffer pH 6.5 and a Cl8 Aqua column. Chiral separation of 9 amphetamine type stimulants was obtained using a highly sulfated gamma-cyclodextrin as a chiral selector. MECC and CZE were compared for the analysis of psilocybin, while a rapid and robust method is presented for the analysis of major opium alkaloids, using dynamically coated capillary …

Using Media Messaging To Promote Healthful Eating And Physical Activity Among Urban Youth, B.J Carter, Amanda Birnbaum, Lisa Hark, Brian Vickery, Charles Potter, Michael P. Osborne

Department of Public Health Scholarship and Creative Works

National trends show consistent increases, as well as racial and ethnic dis- parities, in the prevalence of overweight children and adolescents. Such disparity is evident regarding behaviors such as a poor diet and a lack of physical activity and in the prevalence and outcomes of associated health problems. It has been suggested that grounding interventions in cultural traditions and norms are critical for preventing obesity among ethnic and racial minority youth; however, with some notable exceptions, few community interventions have used this approach. Moreover, urban minority youth may face additional barriers to healthful eating and physical activity behaviors, such as …

High Phosphate (Up To 600 Mm) Induces Pseudohyphal Development In Five Wild Type Candida Albicans, Jacob M. Hornby, Raluca Dumitru, Kenneth Nickerson

Kenneth Nickerson Papers

A method is described for the formation of nearly 100% pseudohyphae populations of wild-type Candida albicans A72. The method employs fungal growth at 37 °C (ca. 5×10⁶ cells/ml) in a glucose–proline–N-acetyl-glucosamine medium supplemented with up to 600 mM phosphate (KH₂PO₄/K₂HPO₄ 1:1) at pH 6.5. Four other strains of C. albicans (MEN, 10261, SG5314 and CAI-4) also formed pseudohyphae under these conditions, although the phosphate response profiles differed in the concentration required for each strain to form pseudohyphae.

Zoological Nomenclature And Kinbote’S Name Of God, Victor Fet

Quorum Sensing In Candida Albicans: Probing Farnesol’S Mode Of Action With 40 Natural And Synthetic Farnesol Analogs, Roman Shchepin, Jacob M. Hornby, Erin Burger, Timothy Niessen, Patrick H. Dussault, Kenneth Nickerson

Kenneth Nickerson Papers

The dimorphic fungus Candida albicans produces extracellular farnesol (3,7, 11-trimethyl-2,6,10-dodecatriene- 1-ol) which acts as a quorum-sensing molecule (QSM) to suppress filamentation. Of four possible geometric isomers of farnesol, only the E,E isomer possesses QSM activity. We tested 40 natural and synthetic analogs of farnesol for their activity in an N-acetylglucosamine-induced differentiation assay for germ tube formation (GTF). Modified structural features include the head group, chain length, presence or absence of the three double bonds, substitution of a backbone carbon by S, O, N, and Se heteroatoms, presence or absence of a 3-methyl branch, and the bulkiness of the hydrophobic …

Eight Gram-Negative Bacteria Are 10,000 Times More Sensitive To Cationic Detergents Than To Anionic Detergents, Soumitra Rajagopal, Nicole Eis, Kenneth Nickerson

Kenneth Nickerson Papers

In liquid culture, eight typical Gram-negative bacteria were ca. 10,000-fold more sensitive to cationic detergents than to the anionic detergent sodium dodecyl sulfate. Cetyltrimethylammonium bromide (CTAB) was inhibitory at concentrations ranging from 0.0006% to 0.01%. Four pseudomonads able to form biofilms were ca. 1000-fold more resistant to CTAB on Luria–Bertani agar plates than they were in liquid culture. A lasI mutant of Pseudomonas aeruginosa was only able to tolerate 0.1% CTAB on Luria–Bertani agar plates but could tolerate 5% CTAB when supplemented with homoserine lactone containing culture supernatants.

What Makes An Animal Choose A Forage, Elizabeth A. Burritt, Frederick D. Provenza

Wildland Resources Faculty Publications

Consider the following scenarios: To cut the costs of ranching a researcher explores feeding cattle ammoniated straw in winter. Some of the cows maintain themselves on the diet while others lose weight, produce less milk and fail to conceive. A producer in Missouri plants a pasture rich in legumes and high in crude protein, yet his cattle prefer moldy hay and endophyte infected tall fescue to the legumes. Why do animals behave this way? Animals are thought to prefer foods that are palatable but what is palatability? We define palatability as the interrelationship between a food's flavor and postingestive feedback …

Pb1191-The Brown Recluse Spider, The University Of Tennessee Agricultural Extension Service

Insects, Pests, Plant Diseases and Weeds

Few things cause as much fear and anxiety in people as the thought of poisonous spiders. Araneophobia, irrational fear of spiders, is widespread in the United States. The brown recluse spider is one of the feared poisonous spiders occurring in Tennessee. This spider is often visualized as an aggressive, bad-tempered monster, just waiting for an opportunity to ambush people. In reality, the brown recluse spider is a shy, retiring spider that does not attack people and usually only bites in response to being injured. Most reported bites occur when putting on old clothing in which the spider is hiding or …

Pb1193-The Black Widow Spider, The University Of Tennessee Agricultural Extension Service

Insects, Pests, Plant Diseases and Weeds

Araneophobia, or an irrational fear of spiders, is common among people in the United States. Few other spiders are as apt to make people uncomfortable as is the black widow. Black widow spiders are very numerous in nearly all parts of the U.S., but cases of reported bites are rare. For the most part, black widows live peacefully in close proximity to humans with little contact. Although both male and female black widow spiders are highly venomous, according to our knowledge, no reports of bites from the males have been recorded.

Pb1303-Managing Pests Around The Home, The University Of Tennessee Agricultural Extension Service

Insects, Pests, Plant Diseases and Weeds

Most household pests are insects and are commonly called “bugs.” Other organisms such as spiders, scorpions, centipedes, millipedes, ticks, sowbugs, pillbugs, mites, rats, mice, snakes, bats, squirrels, birds, molds and fungi may enter homes. In Tennessee, one or more of about 40 common pests are found in every home at one time or another. Even the most conscientious person cannot always avoid an occasional pest infestation.

Development Of Microbial Inocula For Silage Fermentations, Plunkett Clarke

Masters

Silage is the product formed by the fermentation process that occurs when grass is stored anaerobically. Microbial silage inoculants are often added to grass at ensiling in order to improve the silage fermentation. Inoculants normally contain strains of homofermentative lactic acid bacteria. In order to be effective 10 6 viable microorganisms must be added per gram grass ensiled. Literature reports have shown that there are a number of shortcomings associated with inoculants most notably a lack of viability and long lag phases. Therefore, the objective of the research was to improve the quality of silage inoculants. It was hoped to …

Origin And Conservation Genetics Of Threatened Ute Ladies’-Tresses, Spiranthes Diluvialis (Orchidaceae), Allen L. Szalanski, Gerry Steinauer, Richard Bischof, Jessica Lynn Petersen

Department of Animal Science: Faculty Publications

The Ute ladies’-tresses, Spiranthes diluvialis, is listed as a threatened orchid in west-central United States by the Federal government. Information on its origin and patterns of genetic variation is needed to develop effective conservation strategies for this species. DNA sequencing and polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP) was used to evaluate genetic variation and structure of 23 populations of S. diluvialis. In addition, four congeneric species were analyzed to determine possible origins of the putative allotetraploid S. diluvialis. DNA sequencing and PCR-RFLP analysis of the nuclear ribosomal internal transcribed spacer (ITS) and mitochondrial and chloroplast DNA …

Chlorella Virus Pbcv-1 Encodes A Functional Homospermidine Synthase, Annette Kaiser, Michael Vollmert, Dorothea Tholl, Michael V. Graves, James Gurnon, Weimei Xing, Amber D. Lisec, Kenneth Nickerson, James L. Van Etten

Kenneth Nickerson Papers

Sequence analysis of the 330-kb genome of chlorella virus Paramecium bursaria chlorella virus 1 (PBCV-1) revealed an open reading frame, A237R, that encodes a protein with 34% amino acid identity to homospermidine synthase from Rhodopseudomonas viridis. Expression of the a237r gene product in Escherichia coli established that the recombinant enzyme catalyzes the NAD⁺-dependent formation of homospermidine from two molecules of putrescine. The a237r gene is expressed late in PBCV-1 infection. Both uninfected and PBCV-1-infected chlorella, as well as PBCV-1 virions, contain homospermidine, along with the more common polyamines putrescine, spermidine, and cadaverine. The total number of polyamine …
