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
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
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

Auto-fiction and Identity in Esther Tusquets’ Trilogy
No full textThis thesis investigates personal development and identity formation in Esther Tusquets and the female protagonists in her trilogy, composed of El mismo mar de todos los veranos (EMM) (1978), El amor es un juego solitario (AJS) (1979) and Varada tras el último naufragio (VUN) (1980).
Recent autobiographic publications had made it possible to shed light on the author behind the literature and had provided indications that supported a hypothesis of life influencing literature.
This thesis approaches the question of identity formation primarily through the female protagonists in the trilogy. Their emotional and sexual development, analysed in Chapter 2 and 3, is seen as indicatory of a similar developmental path taken by Tusquets. Chapter 2 and 3 therefore focus on the protagonists’ identity development in emotional and sexual terms and elicit further parallels that exist between the literary plot and the author’s life by complementing the analysis with a conceptual background on autobiography, auto-fiction and psychoanalysis in women’s development. The backdrop of auto-fiction suggested that textual analysis of Tusquets’ autobiographic literature should also allow for a margin of scepticism regarding the reliability of its content. The conclusions derived from Chapters 2 and 3, were seen as paramount because they allowed for putting the later analysis of the author on issues, such as love, sex, motherhood, career, solidarity, individuality and independence, into context. The objective of Chapter 4 was to extract Tusquets’ perspective on womanhood and identity put forward in the trilogy. To do so, her definition of femininity, evidenced by her autobiographic works and her novels, was analysed against the backdrop of patriarchal history, thought and theory provided by Marilyn French, Kate Millett and Gerda Lerner.
All this led to a conclusive portrait about Esther Tusquets’, her identity and development in regards to womanhood, as well as, a renewed analysis of her protagonists and their identity formation proces

No full textThe Social Museum (1909), as a centre producer and distributor of statistical information, is analyzed through the figure of its librarian: Cebrià de Montoliu. A quantitative presentation is done of the information section of the Museum describing its products, activities and statistics of use of the service and the type of its users. Also the section of the library specialized in economic and financial information is analyzed, presenting/displaying the statistics of the acquisition, cataloguing, classification and loan of books and magazines. The author settles down a comparison between the work made by the Social Museum and the Comissió Mixta de Coordinació Estadística (Joint Commission of Statistical Coordination) (1969), that later became the Consortium of Information and Documentation of Catalunya (CIDC), and finally, in 1989 the Institut d'Estadística of Catalunya (Idescat)
The long-term impact of cancer: Evaluating psychological distress in adolescent and young adult cancer survivors in Switzerland
No full textObjectives
Adolescents and young adults (AYAs) are diagnosed with cancer during a critical life period full of psychosocial challenges. They may experience a significant impact of the cancer diagnosis on their psychological health, also in the long term. We aimed to (a) evaluate psychological distress in AYA cancer survivors and compare levels of distress with controls and (b) describe socio‐demographic and cancer‐related characteristics associated with psychological distress.
Methods
We sent a questionnaire to AYA cancer survivors (aged 16‐25 y at diagnosis, survived ≥5 y) registered in the Cancer Registry Zurich and Zug, Switzerland. Psychological distress was measured using the Brief Symptom Inventory‐18 (BSI‐18) assessing anxiety, depression, and somatization and a global severity index (GSI) (cutoff score indicating psychological distress: T ≥ 57). Distress levels were compared between survivors and controls. We used logistic regression to determine associations of socio‐demographic and cancer‐related characteristics with distress.
Results
Of 160 AYA cancer survivors, 34 (21%) reported being distressed (27% in women, 17% in men; P = 0.129). Compared with controls, survivors did not report higher levels of distress (all P values > 0.05). Survivors with migration background and survivors with late effects reported higher levels on GSI, somatization, and anxiety. Higher levels of depression were associated with being female, not being in a partnership, and having late effects.
Conclusions
A substantial subgroup of AYA cancer survivors reported psychological distress. Systematically screening for distress and providing psychological follow‐up for survivors at risk may help to provide adequate psychological support
