Design and Analysis of Rotary Positive Displacement Mechanism for Oil-Less Compression
No full textAuthor(s): Holger Roser University of Technology Sydney, Sydney, NSW, Australia In this paper, a simple positive displacement mechanism is investigated, which comprises two counter-rotating meshing rotors within a casing. Although considered for various applications more than a century ago, the basic geometry of this mechanism has not been further explored or adapted to modern gas compressor technology

No full textIf a lion could talk
No full textThis paper treats Wittgenstein's aphorism, "If a lion could talk, we could not understand him," not as absurd, nor as a comment about sensation reports, as various commentators have explained it. Rather, it is argued that an examination of its context(Section xi of Part II of philosophical Investigation) demands an account first of percepion (and of objectivity and subjectivity in the case of 'seeing-as'), and then of meaning (which is not itself an experience, but which otherwise is richly analogous to 'seeing-as'). The concept of 'social space' is then employed to explain the lion's meaning and our (mis-)understanding of him
Extending Transfer in Composition: Exploring a Model for Conceptualizing Rhetorical Problems
No full textThis thesis explores the use of a new rhetorical problem-solving model for writing instruction to create opportunities for abstract thinking and extend the transfer of rhetorical knowledge. The author conducts a qualitative research study on the transfer of rhetorical knowledge by interviewing former students and evaluating their writing samples written in their courses beyond composition. By revisiting the early cognitive writing process research of Linda Flower and John R. Hayes, evaluating the differences between novice and expert writers, and creating corollaries with David Perkins and Gavriel Salomon’s theories on transfer, the author identifies markers for transfer within the rhetorical situation and suggests teaching writing as rhetorical problem solving to extend this transfer to new contexts
The Reality of Fear: Preaching in a Frightened World
No full textFear is a recurrent theme in today’s popular culture. Film director Steven Spielberg’s lifelong work presents the full range from awe and fear to terror, heading towards a deeply humanist approach of overcoming fear. This article puts homiletics into the context of current sociocultural discourse by applying the concept of ‘paradigm scenario’ (Ronald de Sousa) to fear in media culture and preaching. Preaching, like film, works with emotions such as fear and anxiety, initiating strong physical and mental reaction. To preach within a fearful world demands that one be aware of the psychology of fear. As much as preachers are ready to face their personal fears, they abstain from frightening others. At best, preaching is the art of supporting people to live life liberated by the gospel, speaking up against those who create an atmosphere of fear. The gospel provides numerous paradigm scenarios of courage and vision

Attendance to Follow-Up Care in Survivors of Adolescent and Young Adult Cancer: Application of the Theory of Planned Behavior.
No full textPURPOSE
The aim was to study follow-up care attendance in adolescent and young adult (AYA) cancer survivors to investigate: (1) correlates of the intention to attend follow-up care and (2) whether the intention is associated with the actual attendance, applying the theory of planned behavior (TPB).
METHODS
We conducted a questionnaire survey in AYA cancer survivors diagnosed 1990-2005 at age 16-25 years, registered in the Cancer Registry Zurich and Zug, Switzerland, who had survived at least 5 years. Structural equation modeling was applied to investigate TPB-related correlates (attitudes, subjective norms, and perceived behavioral control) of intention to attend follow-up care. Logistic regression analysis was used to study the association between intention and actual attendance.
RESULTS
We included 160 AYA cancer survivors in the study (mean age at study: 34.0 years, mean age at diagnosis: 21.6 years, 98 [61.3%] male). Positive attitudes toward follow-up care (coefficient = 0.32, 95% confidence interval [CI]: 0.05 to 0.60) and supportive subjective norms (coefficient = 0.59, 95% CI: 0.41 to 0.78) were associated with higher intention to attend follow-up care. Perceived behavioral control was not associated with intention to attend (coefficient = -0.13, 95% CI: -0.36 to 0.10), but with actual attendance (odds ratio [OR] = 4.55, 95% CI: 1.83 to 11.31). Higher intention was associated with actual follow-up care attendance (OR = 14.29, 95% CI: 5.80 to 35.21).
CONCLUSION
Positive attitudes and supportive social norms were associated with higher intention to attend follow-up care, and higher intention was associated with actual follow-up care attendance. Increasing awareness of the importance and benefits of follow-up care not only among survivors but also family, friends and healthcare professionals may help increase follow-up care attendance among AYA cancer survivors
Urinary eCG patterns in the mare during pregnancy
No full textBlood and urine samples collected from 12 mares at frequent intervals from 25 to 210 d of pregnancy were analyzed for equine chorionic gonadotropin (eCG). Blood and urine samples were collected daily through two consecutive ovulatory periods from five cyclic mares for comparative purposes. Separate radioimmunoassays (RIA) were developed to detect eCG in the urine and plasma. A simple and quick commercial dipstick enzyme-linked immunospecific assay (ELISA), developed for eCG in the blood, was also utilized in this study to detect eCG in the urine. In the 12 pregnant mares, eCG concentrations in both the plasma and urine as detected by RIA rose significantly on Day 40, peaked by Day 60 and slowly dropped to low levels by Day 200. The dipstick ELISA appeared more reliable for eCG in the plasma than in the urine of the five pregnant mares tested. However, on peak days (50 to 60), both the plasma and urine tested positive in all five mares. Similar eCG profiles were observed when urine samples from seven of the mares were assayed in the dipstick ELISA and RIA. The highest percentage of mares (86%) were positive for eCG by ELISA between Days 65 and 85. The highest concentration of eCG in the urine as detected by RIA was observed between Days 55 and 90. ECG-like immunoactivity was not detected by the ELISA in the urine of cyclic mares, but the RIA showed variable patterns with increases in immunoactivity that could not be correlated with physiological events. In summary, eCG in urine follows a similar profile as the eCG in plasma of mares during their first trimester of pregnancy.PUBM: Print; JID: 0421510; 1989/04/25 [received]; 1989/08/01 [accepted]; 1989/04/25 [received]; 1989/08/01 [accepted]; ppublishSource type: Electronic(1
