The synthesis of monodisperse alkanes with long chains
No full textThis thesis discusses reasons for the interest in monodisperse long chain alkanes and describes attempts, past and present, to synthesise such molecules. Chapter 1 discusses why the synthesis of such molecules are important and the objectives of this project. Chapter 2 reviews the methods previous groups have devised to prepare pure samples of long chain alkanes. In particular, work carried out by Whiting et al. at Bristol, whose scheme formed the basis of the early work in Durham. Chapter 3 describes the work in Durham and improvements which were made to Whiting's method, allowing the synthesis of longer chain lengths and greater quantities of materials to be achieved. Chapter 4 provides a summary of the practical work carried out by the author. Chapter 5 gives experimental details of the work described in Chapter 4
Evaluating physical therapy students' knowledge of and adherence to the ambassador low back pain guideline
No full textPurpose: To examine a process for evaluating physiotherapy (PT) students' knowledge of and adherence to the Ambassador Low Back Pain (LBP) guideline using vignettes. Methods: The study used a cross-sectional survey design. Participants were PT students who had received information related to the guideline as part of their curriculum. Primary measures were responses to questions about the management of four clinical vignettes. Adherence to guideline recommendations was measured by comparing participant scores to a guideline-based set of responses from a physiotherapist involved in developing the Ambassador guideline, which was considered a criterion standard. Results: A total of 74 respondents provided complete data, for a response rate of 89percent; 65 (88percent) reported no knowledge of the guideline. Overall consistency with the criterion standard was high (70percent). Respondents demonstrated high adherence when identifying red flags and deciding whether to refer to another provider. Conclusion: Despite known exposure, knowledge of the guideline was low in this sample of Canadian PT students. Nevertheless, in several key areas, unconscious adherence was high relative to the guidelinebased criterion standard. With minor modifications, the vignettes are suitable for evaluating the Ambassador LBP guidelines in a larger study.Bekkering GE, 2005, QUAL SAF HEALTH CARE, V14, P107, DOI 10.1136-qshc.2003.009357; Bekkering GE, 2003, PHYSIOTHERAPY, V89, P82, DOI DOI 10.1016-S0031-9406(05)60579-2; Bishop Paul B, 2003, Spine J, V3, P442, DOI 10.1016-S1529-9430(03)00152-9; Bishop Paul B, 2006, Spine J, V6, P282, DOI 10.1016-j.spinee.2005.10.008; Cassidy JD, 1998, SPINE, V23, P1860, DOI 10.1097-00007632-199809010-00012; Cutforth G, 2011, PHYSIOTHER CAN, V63, P278, DOI 10.3138-ptc.2009-39P; Di Iorio D, 2000, ARCH FAM MED, V9, P1015, DOI 10.1001-archfami.9.10.1015; Domenech J, 2011, PAIN, V152, P2557, DOI 10.1016-j.pain.2011.07.023; Foster NE, 2011, PHYS THER, V91, P790, DOI 10.2522-ptj.20100326; George SZ, 2011, BMC MED, V9, DOI 10.1186-1741-7015-9-128; Gould D, 1996, J CLIN NURS, V5, P207, DOI 10.1111-j.1365-2702.1996.tb00253.x; GRIMSHAW J, KNOWLEDGE SYNTHESIS; Grol R, 2003, LANCET, V362, P1225, DOI 10.1016-S0140-6736(03)14546-1; Gross DP, 2006, SPINE, V31, P2142, DOI 10.1097-01.brs.0000231771.14965.e4; Gross DP, 2009, DISABIL REHABIL, V31, P871, DOI [10.1080-01443610802355965, 10.1080-014413610802355965]; Harman K, 2009, PHYSIOTH CAN, V61, P88, DOI 10.3138-physio.61.2.88; Harstall C, 2011, J EVAL CLIN PRACT, V17, P693, DOI 10.1111-j.1365-2753.2010.01420.x; Hay EM, 2008, BMC MUSCULOSKEL DIS, V9, DOI 10.1186-1471-2474-9-58; Hayden JA, 2009, J CLIN EPIDEMIOL, V62, P781, DOI 10.1016-j.jclinepi.2008.09.004; Hayden JA, 2010, BEST PRACT RES CL RH, V24, P167, DOI 10.1016-j.berh.2009.12.005; Hill JC, 2011, LANCET, V378, P1560, DOI 10.1016-S0140-6736(11)60937-9; Hill JC, 2010, EUR J PAIN, V14, P83, DOI 10.1016-j.ejpain.2009.01.003; Hockings RL, 2008, SPINE, V33, pE494, DOI 10.1097-BRS.0b013e31817ba3bb; Ikezawa Y, 2010, J OCCUP REHABIL, V20, P367, DOI 10.1007-s10926-010-9230-z; Institute of Health Economics, 2009, GUID EV INF PRIM CAR; Koes BW, 2010, EUR SPINE J, V19, P2075, DOI 10.1007-s00586-010-1502-y; Main CJ, 2011, PHYS THER, V91, P820, DOI 10.2522-ptj.20110060; Peabody JW, 2000, JAMA-J AM MED ASSOC, V283, P1715, DOI 10.1001-jama.283.13.1715; Peabody JW, 2004, ANN INTERN MED, V141, P771; Poitras S, 2007, J EVAL CLIN PRACT, V13, P412, DOI 10.1111-j.1365-2753.2006.00725.x; Poitras S, 2012, SPINE, V37, P1252, DOI 10.1097-BRS.0b013e31824b6adf; Poitras S, 2005, PHYS THER, V85, P1168; Portney LG, 2009, FDN CLIN RES APPL PR; Rainville J, 2000, SPINE, V25, P2210, DOI 10.1097-00007632-200009010-00012; RASHIQ S, 2006, BMC MED EDUC, V6, P1; Rutten G, 2009, J CLIN EPIDEMIOL, V62, P167, DOI 10.1016-j.jclinepi.2008.04.004; Rutten GM, 2010, PHYS THER, V90, P1111, DOI 10.2522-ptj.20090173; Rutten GMJ, 2006, J EVAL CLIN PRACT, V12, P491, DOI 10.1111-j.1365-2753.2006.00699.x; Schreiber J, 2005, INTERNET J ALLIED HE, V3, P1; Shah R, 2010, OPHTHAL PHYSL OPT, V30, P209, DOI 10.1111-j.1475-1313.2010.00713.x; Turner Patricia A., 1999, Physiotherapy Theory and Practice, V15, P235, DOI 10.1080-095939899307649; van Tulder MW, 2004, SPINE, V29, pE357, DOI 10.1097-01.brs.0000137056.64166.51; Webster BS, 2005, J GEN INTERN MED, V20, P1132, DOI 10.1111-j.1525-1497.2005.0230.x11
Towards the Theatre: Opasnyi Povorot (Dangerous Corner). The 1939 Production by G.M. Kozintsev at the Leningrad Comedy Theater
No full textThe subject of this research is the first production in a series of theatrical works by G.M. Kozintsev (1905–1973) of the late 1930s — early 1950s, which are fundamentally important both in his creative biography and in the history of Soviet theatre of that era. The author suggests that the entry of the famous film director into theatre was caused by the desire to find a way out of a creative impasse.
The director’s appeal to the play of the modern English novelist and playwright J.B. Priestley and its controversial interpretation were driven by the dramatic atmosphere of the late 1930s. The eccentric grotesque of the play and its pamphlet character, which was insisted on by the director, are considered as a parody of tragedy by the author of the research. This reveals a fundamental connection between the production under consideration and the subsequent successful experiments of G.M. Kozintsev in the field of theatrical Shakespeareana. The article draws attention to the fundamental connection between the style of the production and the general style of the Leningrad State Comedy Theatre developed by its director — the outstanding theatre director and set designer, G.M. Kozintsev and E.L. Schwartz’s friend and associate, N.P. Akimov. The research is based on the performance reviews, testimonies of the participants of the performance, contemporaries close to the director (especially the playwright and screenwriter E.L. Schwartz and the long-term G.M. Kozintsev’s co-author L.Z. Trauberg), as well as the surviving radio version of the play

No full textStevin Outlet Sluices: Wave impact under a beam
No full textThe Dutch department of Public Works had a problem regarding wave impacts on a beam in the Stevin outlet sluices, located in the Afsluitdijk. Wave impacts on this beam could also cause a peak pressure on the barrier gate, just behind the beam. The numerical program ComFLOW and physical scale experiments were used to predict the wave impacts for different hydraulic conditions (i.e. wave height, wave period and water level). The research questions were: 1. How is the wave load on the northern gates depending on the presence of the military beam? 2. How large is a wave impact load on the bottom of the military beam in the Stevin outlet sluices? 3. How well can the numerical model ComFLOW and physical modelling be used to determine the wave impact on the bottom of the military beam in the Stevin outlet sluices? 2D scaled experiments were performed making use of a model with the (simplified) geometry of the Stevin outlet sluices and regular waves. It was found that the largest wave impacts occurred for water levels equal to the bottom plane of the beam or slightly under it. This happened for the shortest waves in the test domain. The largest pressure measured on the beam was approximately 50 kPa or 35H, with H representing the incident wave height in front of the model. It was also found that the spread in the peak pressures for one single experiment was large. The results of the measured impulse per peak showed far less spread. The effect of wave impacts under the beam was also found on the vertical wall under the beam. The actual pressures however were less and they were decreasing with increasing depth. Besides physical wave impact testing, a few experiments were performed with the beam removed from the model. This resulted in wave simply running up the vertical wall of the model. They did not cause a wave impact. The measurements of both type of experiments, with and without a beam, were compared. This revealed that the total wave impulse on the gate was not affected by the presence of the beam. However the distribution of the pressure within a single wave period was significantly different. In case of a beam, a large impact peak was observed, whereas the other wave only showed a small hump caused by the deflected flow against the vertical wall. When the calculated and measured wave impact results were compared it became clear that ComFLOW underestimated the peak pressures by a factor 2 to 20 for the pressures on the impact plane. The same was done for the peak impulse. This showed that the impulse of the peak on the impact plane were underestimated by a factor 2 at most. These results confirmed that the used grid was too coarse for the program to model the physics correctly. The main conclusions to the research questions were: 1. The presence of the military beam causes a different distribution of the force on the gate within a wave period. The total amount of impulse is more or less the same as for the situation without a beam. With the military beam, a wave impact results in a peak force on the gate. Without the beam, there will be no peak force. 2. The largest measured wave impact pressure is 35H. 3. Both ComFLOW and physical modelling can be used to predict wave impacts for the geometry of Stevin outlet sluices. Much care should be taken when modelling and much attention should go to the input parameters of the program.Hydraulic StructuresHydraulic EngineeringCivil Engineering and Geoscience
A Professional Author-How G.M. Glaskin Earned a Living
No full textWestern Australian author Gerald Marcus Glaskin (GMG; 16 December 1923-11 March 2000) wrote from life, using his experiences to continually expand his creative repertoire. In one sense, this was to be his downfall, as his life was unconventional for his time. Because he mined own experiences so much in his creative writing, his works eventually moved out of mainstream markets. However, this paper focuses on his financial success as a writer, details of which can be documented through study of the meticulous records kept by both GMG and his publisher, Barrie & Rockliff of London. Other scholarly analysis of the income received by authors is limited. Katherine Bode (2012) does not deal with the subject in her otherwise comprehensive quantitative analysis of Australian publishing. What little is known about the income of professional authors from this or other periods, and whether they were able to survive on the proceeds of their writing, is incidental to other research
A more comprehensive and commanding delineation: Mary Shelley's narrative strategy in Frankenstein
No full textThis thesis argues that the first edition of Frankenstein challenges conventional reading by employing what Simpson in Irony and Authority in Romantic Poetry calls Romantic irony, where the absence of a stable 'metacomment' precludes an authoritative reading. The novel hints at such readings but prevents them. The insights offered by Tropp's Mary Shelley's Monster, Baldick's In Frankenstein's Shadow, Poovey's The Proper Lady and the woman writer and Swingle's, 'Frankenstein's Monster and its Relatives: Problems of Knowledge in English Romanticism' are considered, but none recognises the full implications of the instability deriving from multiple first- person narratives. Clemit's The Godwinian Navel acknowledges the novel's indeterminacy, but reads a specific ideological purpose in it. Paradise Last provides a language to describe the relationship between the monster and Frankenstein, but proves too unstable to fix identity or establish moral value. Similarly, Necessity ultimately fails to provide a stable explanation in terms of cause and effect. The status of nature shifts between foreground and background, never allowing final definition. These uncertainties destabilise knowledge which is compromised by its provisional nature: no authoritative reading is possible, yet the novel has narrative coherence. The reader is encouraged to try to develop a reading the structure prevents. The radical nature of the first edition is highlighted by comparison with the 1831 edition, which removes much of the ambivalence and gives the novel a clearer morality. The novel challenges conventional methods of deriving authority by disturbing the reader's orthodox orientation in the world around him' (Simpson) in order to afford 'a point of view to the imagination for the delineation of human passions more comprehensive and commanding than any which the ordinary relations of existing events can yield' (Mary Shelley)

3D eclipse mapping
No full textA light curve modelling and fitting program is presented for
cataclysmic variable stars and related objects. It allows modelling
of a three-dimensional disk in conjunction with the Roche-lobe
filling secondary star, thus rendering it a very general tool
for light curve analysis.
Optimization of the solution is based on the maximum-entropy
algorithm. Some bench-mark tests are presented, and the general
applicability of the program is explored.
The program is used here to study the problem of reconstructing
the brightness distribution on flaring accretion disks from
eclipse light curves, and the results are compared with those
obtained using the well-established standard technique of
flat-disk eclipse mapping.
A previous study suggested that erroneous radial temperature
profiles were obtained with flat-disk eclipse mapping.
It is shown here that flat-disk eclipse mapping does reproduce
the radial brightness structure of flared accretion disks
very well, provided that the inner disk is not obscured by the outer
rim of the disk
