Ground test experience with large composite structures for commercial transports

The initial ground test of each component resulted in structural failure at less than ultimate design loads. While such failures represent major program delays, the investigation and analysis of each failure revealed significant lessons for effective utilization of composites in primary structure. Foremost among these are secondary loads that produce through-the-thickness forces which may lead to serious weaknesses in an otherwise sound structural design. The sources, magnitude, and effects of secondary loads need to be thoroughly understood and accounted for by the designers of composite primary aircraft structures

The Experiences of QuestBridge Scholars at Elite Universities

In this dissertation, I examined the experiences of QuestBridge Scholars attending three different elite universities that enroll more students from the top income quintile than from the lowest three income quintiles combined. The universities attended by participants in this study are among the few that are both need-blind and that fully meet students’ demonstrated financial need through grant and scholarship aid. Additionally, these universities have acceptance rates of no more than 10%. The QuestBridge organization’s mission is to match high-achieving, low-income students with elite institutions. Data from participants were collected through an audio and video recorded interview using a semi-structured protocol. Interviews were transcribed and then coded using an iterative open coding process to identify themes. The themes that emerged were: changing relationships with family and friends from before college, finding support while enrolled, the transition from family of origin to elite higher education, experiencing privilege, campus involvement, social belonging, navigating elite higher education, and academic adjustment and impostor phenomenon. These themes suggest that QuestBridge Scholars experience something akin to class culture shock when they enter the world of elite higher education. This study is significant because it focuses specifically on QuestBridge Scholars who have been successful at a highly selective subset of QuestBridge institutions with high income disparity, where success is defined by having reached second-semester junior status or having graduated. The focus on those who attend or attended highly selective institutions and who are succeeding suggests that these students might have insights that would smooth the path for others like them. This study may also have implications for practice for highly selective institutions that admit QuestBridge Scholars and other low-income students. Finally, in this study, I explored participants’ perceptions of socioeconomic class, with results suggesting that the transition from family of origin to elite higher education causes changes in self-perception and behavior

Dear vulnerability … writing toget-her to escape and resist the neoliberal university

I am lost. My writing is lost. I feel isolated, under pressure, trapped in a cage. My writing is measured and molded, suffocating in a corset of norms and expectations in the neoliberal university. In a collective diary, I can share my experiences, ponder on my feelings. I breathe, I survive, I resist. And as I write, I open up. As I write, I find myself, I find ot-hers. Through my words, sentences, and pages, I embrace my vulnerabilities: insecurity, courage, relating, becoming. I write collectively, stronger toget-her. I write to offer new understandings, to change and resist the neoliberal university. Will you join me?.</p

Diagnostische Bedeutung der Proteinbindung von Plasmacortisol, bestimmt durch Dextrangelfiltration

1. Mittels Dextrangelfiltration wurde nach Inkubation von markiertem Cortisol und Plasma der proteingebundene und der sog. freie Anteil (%) des endogenen Plasmacortisols ermittelt und bei gleichzeitiger fluorimetrischer Bestimmung der 11-OHCS auch die Menge proteingebundenen, bzw. sog. freien Cortisols (µg-%) berechnet. 2. Die diagnostische Brauchbarkeit der Methode wurde bei Patienten mit Nebennierenrindeninsuffizienz, mit Hypophysentumoren, nach Hypophysektomie, mit Cushing-Syndrom mit der fluorimetrischen Bestimmung der 11-OHCS verglichen. Die einfache Bestimmung der Cortisolbindung war bei hypophysektomierten Patienten der Bestimmung der 11-OHCS überlegen und entsprach der aufwendigeren ACTH-Belastung. 3. Falsch hohe fluorimetrische 11-OHCS-Spiegel im Plasma unter Spirolacton- oder Oestrogenbehandlung und in der Gravidität lassen sich durch Bestimmung der Cortisolbindung klären. Bei Schilddrüsenüberfunktion war das sog. freie Cortisol im Plasma relativ und absolut vermehrt, bei Schilddrüsenunterfunktion fand sich eine Zunahme des plasmaproteingebundenen Cortisols.1. Following incubation of labeled cortisol and plasma the percentages of protein bound and socalled free endogenous cortisol were determined by means of dextran gel filtration. 2. The diagnostic value of this method was compared with fluorimetric determinations of 11-OHCS for patients with adrenal insufficiency, Cushing-Syndrome, pituitary tumors and after hypophysectomy. In hypophysectomized patients the simple determination of protein bound cortisol was found to correlate well with diagnostic ACTH-infusion tests and to be more sensitive than fluorimetric determinations of 11-OHCS in 9 a.m. plasma. 3. Falsely elevated fluorimetric values of plasma 11-OHCS in patients treated with spirolactone or estrogens, resp. during pregnancy may be recognized through determination of cortisol binding. — In thyrotoxicosis socalled free cortisol was elevated, both relatively and absolutely; in hypothyroidism an increase of protein bound cortisol was found
