Analysis of Stability Indices for Severe Thunderstorms in the Northeastern United States

REA Auditado

In operational forecasting, many indices are used to assess the stability of the atmosphere and predict the likelihood of severe thunderstorm development. One of the shortcomings of many of these indices is that they are mainly based on observations from the southern Plains. Severe thunderstorms can occur in the northeastern United States in conditions which significantly differ from those expected in the Plains. Few attempts have been made to modify these indices for thunderstorms in the Northeast. A new set of values specifically for use in the Northeast are computed.

The Chemistry of Color Tie Dye

REA Auditado

The activity introduces students to acids and bases using the juice of a red cabbage as an indicator. The activity includes testing what happens to the indicator when acids and bases are added, and what happens when acids and bases are mixed. The students test several mystery solutions and guess their identity by testing each with the acid/base indicator. Using different colored dyes from the activity, students finish by making their own tie-dye handkerchief.

Morphology and Pathology of the Cysteine Dioxygenase Knockout Mouse: Evaluating Skeletal and Connective Tissue Abnormalities

REA Auditado

Cysteine catabolism is dependent upon cysteine dioxygenase (CDO), a thiol dioxygenase encoded by the gene CDO1. The clinical literature and, more recently, the study of CDO polymorphisms in disease and control populations have illustrated a strong association of impaired metabolism of cysteine to sulfate and taurine and/or CDO loss-of-function mutations with a variety of autoimmune and neurodegenerative diseases. The Stipanuk research group has recently generated a germ-line CDO knockout (CDO-/-) mouse that clearly has metabolic and phenotypic abnormalities.

Public Opinion of the Use of Eminent Domain for Phase Two of the Cayuga Waterfront Trail

REA Auditado

Eminent domain, the right of a government to take private property for public uses, was originally intended for projects with clear public purposes, such as the construction of utility lines. However, the use of eminent domain has become increasingly controversial because it has also been used for more discretionary projects, such as recreational trails. The purpose of this study was to gain insight on public opinion of the use of eminent domain for Phase Two of the Cayuga Waterfront Trail in Ithaca, NY.

An Analysis on the Impacts of Ice Cover on Two Eastern Great Lakes Lake Effect Snow Events

REA Auditado

Analysis of lake effect snow events is important due to the economic effects lake effect events can have on a region, such as the replenishment of watersheds used in agricultural purposes. It is generally accepted that a number of factors play a role in the persistence and intensity of lake effect snow events, such as ice formation of the surface of the lake, but only recently has that relationship begun to be thoroughly examined.

Crystallographic Studies on Mutants of Trichomonas vaginalis Purine Nucleoside Phosphorylase

REA Auditado

Trichomonas vaginalis is a protozoan human parasite that causes trichomoniasis, one of the most common sexually transmitted diseases in the world. The toxicity of current therapies as well as drug resistance exhibited by certain T. vaginalis strains underscores the need for new treatment options. One possibility involves the purine salvage pathway, which is well known for its importance in organisms.

Retronasal and Oral-Cavity-Only Responses to TRPM8 Odorants

REA Auditado

Retronasal (retro) and/or oral-cavity-only (OCO) smelling of vapor-phase agonists for the trigeminal chemoreceptive ion channel TRPM8 was studied. In a retro and OCO identification experiment, 1 of 6 previously practiced identifications (ID) was selected on a computer display under forced-choice conditions. Analyses of variance (ANOVA) found differences across odorants and retro and OCO, and for retro and OCO separately. Within retro smelling, median correct ID and modal ID (in parentheses) for eucalyptol was 100% (ointment), different from all other odorants.

The Early Innate Intestinal Immune Response to Listeria monocytogenes in BALB/c Mice

REA Auditado

Listeria monocytogenes is a facultative intracellular bacterial pathogen capable of escape from vacuoles and intercellular spread. Escape from vacuoles is in part mediated by a broad-range phospholipase C (PC-PLC) whose activity is regulated by pH. Deletion of the sequence coding for the PC-PLC propeptide (plcB?pro) generates an enzyme that is constitutively active. Results from oral mouse infections indicated that L. monocytogenes plcB?pro is cleared more rapidly from the intestinal tissues than wild-type bacteria.

Biochar as an Amendment to Improve Soil Fertility

REA Auditado

Biochar, a soil amendment resulting from pyrolysis of biomass, can improve soil texture and increase nutrient and water retention. Biochar produced from various feedstocks, each under a range of temperatures was used to amend field soil at 0.2, 0.5, 2.0, and 7.0% (w/w) application rates (equivalent to 2.6, 6.5, 26, and 91 t biochar ha-1) for growing maize in a greenhouse pot trial. Unamended controls were grown at 60, 80, 90, 100, and 140% of recommended fertilizer application rates to compare the effects of biochar against fertilizer effects.

Canaries of the Pond and Stream

REA Auditado

Youth will explore ponds and/or streams to collect and identify the various species that are living there. The diversity of organisms found in an aquatic environment is an indicator of habitat quality and overall environmental quality. The presence or absence of certain macroinvertebrates (large organisms that don't have backbones, such as insects) tells us something about the health of the aquatic ecosystem.
