An Examination of "The Martian" Trajectory

This analysis was performed to support a request to examine the trajectory of the Hermes vehicle in the novel "The Martian" by Andy Weir. Weir developed his own tool to perform the analysis necessary to provide proper trajectory information for the novel. The Hermes vehicle is the interplanetary spacecraft that shuttles the crew to and from Mars. It is notionally a Nuclear powered vehicle utilizing VASIMR engines for propulsion. The intent of this analysis was the determine whether the trajectory as it was outlined in the novel is consistent with the rules of orbital mechanics

The Effects of Postsecondary Correctional Education

Presents findings on the effect of prison-based postsecondary education on offenders during incarceration and on post-release employment and recidivism. Explores offenders' and stakeholders' views on the value and challenges of such programs

Power and Propulsion Element (PPE) Spacecraft Reference Trajectory Document

This document captures example reference trajectories for the PPE including a reference delivery orbit and orbit maintenance, an example cislunar orbit transfer and end-of-mission (EOM) disposal trajectory. The flexibility of electric propulsion offers, by its low thrust nature, multiple different trajectory options to transfer from one orbit to another. The trajectories captured in this document are representative examples of a low thrust transfer from the NRHO and to multiple cislunar orbits. This document provides a consistent set of data from mission design to be used in the design of the vehicle capable of flying the trajectory described. The data in this document will be used to create conference papers. In order to do so, we are ending this document through for external release

Brown Mid-Rib Corn Population Trial

Brown mid-rib (BMR) corn hybrids are of interest to many growers in the Northeast who would like to maximize milk production on homegrown forage. BMR corn has a naturally-occurring genetic mutation that leads to less lignin in the stalk and makes corn silage more digestible. Corn yields can be highly dependent on population, and it is generally recommended to plant BMR corn at lower populations than conventional silage corn. BMR corn has always been considered to be more prone to lodging due to its lower lignin content, and lower populations allow for less stress on each individual plant. However, optimal populations for the Northeast have yet to be developed. With this in mind, the University of Vermont Extension Northwest Crops & Soils Program conducted a field experiment in 2013 designed to evaluate the yield and quality performance of a BMR corn hybrid at three different populations across two different varieties. The data presented are only representative of one year, but this information can be combined with other research to aid in making agronomic decisions for BMR corn in the Northeast

Forage Brassica Variety Trial

Forage brassica can provide a near-concentrate type diet late in the grazing season. This allows for an extra grazing opportunity after annual row crops are harvested, and establishes forage to fill a gap in feed quality and supply. These crops can provide a high-quality feed in a short period of time, fitting well into rotations of other crops, extending the grazing season, and reducing reliance on expensive commercial feed inputs. In 2013, the University of Vermont’s Northwest Crops & Soils Program conducted a forage brassica variety trial to evaluate yield and quality of this annual crop

Brown Mid-Rib Corn Variety Trial

Brown mid-rib (BMR) corn has a lower lignin content than other silage corn varieties. The lower lignin content increases the fiber digestibility (NDF digestibility) of the corn silage. Increases in NDF digestibility lead to increased in dry matter intake, milk production, milk protein content, and better body condition. Several studies have reported that for every one percentage point increase in NDF digestibility fed to dairy cattle there will be a 0.50 lb per day increase in milk production. Feeding BMR corn silage is a means to increase NDF digestibility and milk production. Since 2010, the University of Vermont Extension Northwest Crops & Soils program has conducted research trials to evaluate BMR corn silage varieties. In 2012, the trial included 10 varieties from three different seed companies. While the information presented can begin to describe the yield and quality performance of these BMR corn varieties in this region, it is important to note that the data represent results from only one season and one location.

Aging, Emotion, Attention, and Binding in the Taboo Stroop Task: Data and Theories.

How does aging impact relations between emotion, memory, and attention? To address this question, young and older adults named the font colors of taboo and neutral words, some of which recurred in the same font color or screen location throughout two color-naming experiments. The results indicated longer color-naming response times (RTs) for taboo than neutral base-words (taboo Stroop interference); better incidental recognition of colors and locations consistently associated with taboo versus neutral words (taboo context-memory enhancement); and greater speed-up in color-naming RTs with repetition of color-consistent than color-inconsistent taboo words, but no analogous speed-up with repetition of location-consistent or location-inconsistent taboo words (the consistency type by repetition interaction for taboo words). All three phenomena remained constant with aging, consistent with the transmission deficit hypothesis and binding theory, where familiar emotional words trigger age-invariant reactions for prioritizing the binding of contextual features to the source of emotion. Binding theory also accurately predicted the interaction between consistency type and repetition for taboo words. However, one or more aspects of these phenomena failed to support the inhibition deficit hypothesis, resource capacity theory, or socio-emotional selectivity theory. We conclude that binding theory warrants further test in a range of paradigms, and that relations between aging and emotion, memory, and attention may depend on whether the task and stimuli trigger fast-reaction, involuntary binding processes, as in the taboo Stroop paradigm

Organic Spring Wheat Planting Date Trial

The local food movement has revived otherwise historical crops in Vermont including small-scale grains. As the demand for local organic wheat has risen over the last few years, University of Vermont Extension has been developing best agronomic practices for wheat production. In an organic system, weed management can be one of the biggest challenges. One strategy to manage weeds is to modify planting dates. Early planting dates can establish a crop prior to weed flushes, while a late-planted crop can avoid some weed species. Planting date can also have an overall impact on both grain yield and quality. Certain wheat varieties may respond better to earlier or later planting dates. At this time, there is minimal data to document optimum spring wheat planting dates for the Northeast. The objective of this project was to determine the effect of planting date on the yield and quality of multiple spring wheat varieties
