Analysis of the Effects of Temperature and Velocity on the Response Time Index of Heat Detectors

Recent revisions to NFPA 72, the National Fire Alarm Code, have specified the response time index (RTI) as the sensitivity listing for heat detectors. Originally derived as a sprinkler sensitivity rating, there has been little work performed to validate the use of the RTI rating for heat detectors. RTI values are determined by plunging the devices into a hot wind tunnel at 200 C (392 F) and 1.5 m/s (4.9 ft/s). These test conditions are unrealistically severe for the majority of expected ceiling jet profiles. While the RTI correlation is purported to be independent of temperature and velocity, data from previous studies indicates otherwise. This study examined the effects of low temperature and low velocity plunge test conditions on the constancy of the RTI for several common heat detectors. The RTI correlation was found to be inconsistent across temperature and velocity test conditions

Eliot as Satirist

T. S. Eliot is seldom considered a satirist, even though satirical elements have long been perceived in his early poetry, most notably by Hugh Kenner and W. B. Yeats. Building on the scholarship from the last two decades which explores Eliot’s relationship with popular culture, as well as the recently published letters from Eliot’s early life and the drafts of The Waste Land, this dissertation argues that Eliot’s earliest impetus was towards satire, and that his early career was a development, and finally an abandonment, of this mode. The first section surveys Eliot’s earliest satirical poetry from Inventions of the March Hare to the controversial ‘King Bolo’ verses, contending that Eliot’s initial satirical project was to provoke the particularly American puritanical culture that he grew up in. The second chapter explores Eliot’s development of this satirical impetus as it relates to Poems 1920, particularly as it manifests in Eliot’s defences of Wyndham Lewis, Ben Jonson, and Francis Cornford’s theory of ancient ‘tragi-comedy’. The concluding chapter deals with The Waste Land, firstly with the earliest reviews that correctly perceive Eliot’s satirical tone in the poem, and then with Ezra Pound’s edits, contending that the pair’s differing opinions on the nature and purpose of satire motivated this editorial process and Eliot’s eventual abandonment of the form

The Impact of Personality Traits on Panic Buying Behavior

We are interested in panic buying behavior during a pandemic within an undergraduate population. Since there is minimal research on COVID-19, we hope that our research will contribute to further investigations on this pandemic and other related psychological concepts and issues within the field. This is important because previous research has studied the relationship between buying behavior and natural disasters; however, there is a small amount of literature on COVID-19 because this is a new and rising topic that is changing day by day. Preparedness and risk perception are in tandem. We want to increase people’s knowledge about how to prepare for disasters and increase their own risk perceptions for future disasters scenarios. Past literature led us to focus primarily on three distinct personality traits: extraversion, conscientiousness, and neuroticism. The importance of researching personality traits shows us that there is a guide to an individual’s impulse buying behaviors (Olsen, Tudoran, Honkanen, & Verplanken, 2016). One specific trait, extraversion, was shown to be positively associated with panic excess buying behaviors as well as neuroticism. Previous research also found that the Five Factor Model effectively determined the risk for panic buying which originated from certain personality traits (Otero-López & Villardefrancos, 2013). This previous literature led us to develop our own research of how personality traits impact panic buying behaviors. We predict that if all participants score high on the 3 traits we are interested in, it will be positively be associated with an increase in panic buying behavior

Does stroke location predict walk speed response to gait rehabilitation?

Objectives Recovery of independent ambulation after stroke is a major goal. However, which rehabilitation regimen best benefits each individual is unknown and decisions are currently made on a subjective basis. Predictors of response to specific therapies would guide the type of therapy most appropriate for each patient. Although lesion topography is a strong predictor of upper limb response, walking involves more distributed functions. Earlier studies that assessed the cortico-spinal tract (CST) were negative, suggesting other structures may be important. Experimental Design: The relationship between lesion topography and response of walking speed to standard rehabilitation was assessed in 50 adult-onset patients using both volumetric measurement of CST lesion load and voxel-based lesion–symptom mapping (VLSM) to assess non-CST structures. Two functional mobility scales, the functional ambulation category (FAC) and the modified rivermead mobility index (MRMI) were also administered. Performance measures were obtained both at entry into the study (3–42 days post-stroke) and at the end of a 6-week course of therapy. Baseline score, age, time since stroke onset and white matter hyperintensities score were included as nuisance covariates in regression models. Principal Observations: CST damage independently predicted response to therapy for FAC and MRMI, but not for walk speed. However, using VLSM the latter was predicted by damage to the putamen, insula, external capsule and neighbouring white matter. Conclusions Walk speed response to rehabilitation was affected by damage involving the putamen and neighbouring structures but not the CST, while the latter had modest but significant impact on everyday functions of general mobility and gait

A novel adaptation facilitates seed establishment under marine turbulent flows

Seeds of Australian species of the seagrass genus Posidonia are covered by a membranous wing that we hypothesize plays a fundamental role in seed establishment in sandy, wave swept marine environments. Dimensions of the seed and membrane were quantified under electron microscopy and micro-CT scans, and used to model rotational, drag and lift forces. Seeds maintain contact with the seabed in the presence of strong turbulence: the larger the wing, the more stable the seed. Wing surface area increases from P. sinuosa \u3c P. australis \u3c P.coriacea correlating with their ability to establish in increasingly energetic environments. This unique seed trait in a marine angiosperm corresponds to adaptive pressures imposed on seagrass species along 7,500 km of Australia’s coastline, from open, high energy coasts to calmer environments in bays and estuaries
