Blank space in western Art History and visual culture is something that has tended to be either explained away, or ignored. Pictures that do not depict challenge the visual basis of the ego and its others, confronting what I call the 'Phallic reader' (who sees according to the logic and rules of the Phallogocentric system he inhabits) and potentially disturbing his sense of the visible. The Phallic reader, the visible and the seeing ego's sense of how to see, meet in what I call the 'psychic surface'. Deploying this notion of a 'psychic surface' allows for readings which move on from the potentially confining logic of the Phallus. Paradoxically, the psychic structure of monochrome's liminal blankness is homologous to the indeterminate Mixed Race subject, whose body transgresses not only the foundational historical binarism of 'Black/White', but also Lacanian psychoanalysis. This thesis aims to concentrate on exploring blank spaces, with particular reference to the monochrome within western Art History. Building on the considerable work since at least the 1960s that critiques the binary logocentrism of Eurocentric, Hegelian-originated Art History, this thesis aims to explore the specific ways monochrome evades, undermines and tricks commonly accepted 'groundrules' of Art History. The Phallic reader is severely restricted in understanding that which falls outside of the signifying logic of a particular system of Art History that follows a binary, teleological and Phallogocentric course. Both monochrome and the Mixed Race subject fall outside of this logic, as both contain the structure of the trick. In each case, the trick is activated in the tension between the prychica nd the opticals urfaces. I suggestt hat monochrome's psychic space is pre-Phallic, a space of eternal deferral of meaning, a space that playfully makes a nonsense of binary structures. Psychoanalysis is largely used here as an analytic tool, but also appears as an object of critique. Art History provides an anchor for the optical surfaces under discussion. Theories of 'radical superficiality' both contradict and complement these ways of theorising the psychic surface. The trick/ster is a significant/signifiant means of deploying interdisciplinary methodologies to negotiate this difficult terrain between Black, White and monochrome. An interdisciplinary approach also enacts the psychic structure of indeterminacy of my objects of study. I hope that by proposing a potential transgressive power for those indeterminate things that continue to confound the binary systems that aim to contextualise and confine them, I will contribute to the areas of Visual Culture and 'Race' Theory.

The core project within my PhD research has been the development of a system as an extension of existing media facades that allows me to test the representation of information and ideas as 'form' within space that is constantly generated and regenerated as a result of fresh input. The hypothesis is that this real time reconfiguration of space using light offers a variety of new perceptions ranging from information sharing to public art never experienced previously. During my research, I have established an extensive body of evidence that points to a growing scholarship around the details and impacts of media façade technological developments and the content displayed on them. In the thesis I define the boundaries of these technology shifts and enhanced content combinations limited to 2 dimensions. In my research I consider the technical and media implications of extending conventional 2D screens which are limited currently to architectural cladding into a 3D ma trix thereby causing an alteration to spatial perception through the content animating the 3D matrix. The core research-question is: When weaving together architecture and electronically applied and managed imagery, are their respective properties successfully interchanged to the extent that they mutually create a new architectural zone in constant flux, generated and regenerated through content that never stands still? I have undertaken four projects to develop my research hypothesis. I have developed a prototype system which, with the use of a 3D light-point matrix, alters space. The prototype system has then been applied in an architectural context, tested by applying 'designed' content to it. Lastly I have experimented with writing software 'applets' for a third party to adapt their own input for display purposes. I argue that with such a prototype system, a shift from an autoplastic determinated architecture to an alloplastic indeterminate architecture is possible [Goulthorpe, 1999]. This is a significant shift for architecture beyond the scope of a single PhD. I have concentrated within my area of expertise: media and architecture. By experimenting with a prototype system and limiting the scope of my research to examining the shift from auto to alloplastic architecture, I can consider whether this shift can be achieved through the manipulation of content alone and not rely on the appearance and status of the associated hardware.

Let F be a distribution function and {m1,m2,m3...} be its moments. The moment problem is to know whether the moments {m1,m2,m3...} determine the distribution function F. In general, the sequence of moments does not always determine the distribution function. So the conditions for a distribution function to be moment-determinate are investigated. We get a result concerning the discrete distribution function.

INDETERMINATE DOMAIN (IDD) genes encode a large family of putative transcription factors characterized by four different zinc finger motifs in a conserved arrangement. In Arabidopsis thaliana there are 16 IDD genes designated AtIDD1-AtIDD16. Microarray database expression resources show that AtIDD1 transcripts are present at high levels in dry seed and in response to abscisic acid. Transcripts present in dry seed at high levels have previously been shown to play roles in later stages of seed development or as provisions necessary for the resumption of metabolic activity following seed dormancy. Here I show that lines with constitutive expression of AtIDD1 have decreased and increased sensitivity to the phytohormones abscisic acid and gibberellic acid, respectively, when applied exogenously. Additionally, plants overexpressing AtIDD1 have altered mucilage extrusion and seed coat morphology. Altered seed coat morphology was also observed In constitutive AtIDD1 knock down lines. Therefore, these phenotypes could indicate that AtIDD1 plays a regulatory role in seeds during seed development and/or germination.

The purpose of this paper is to present proofs for six cases of L'Hospital's Rule for the evaluation of indeterminate forms. It is also a purpose to reduce to one of these six cases some other indeterminate forms to which L'Hospital's Rule is applicable. In the course of presenting these proofs several theorems and definitions will be used without proof.

Background The conventional ileostomy can be avoided. Many attempts have been performed. The first successful solution was the continent ileostomy- Kock pouch. The high rate of complications and revisions some experienced forced surgeon to try to restore the continence by the mechanism of the anus involving an ileal pouch. Both procedures afterwards documented excellent functional outcome, but the complication rates were not negligible and the long-term failure rate were increasing. Different surgical refinements were done and the risk factors for complications and failures were investigated as experience and materials increased. Restoring of the integrity of anal function and the succsess of the ileal pouch-anal anastomosis shadowed the practise of the forerunner: the continent ileostomy reservoir. This latter procedure was more demanding and seemed in the first year of ileal pouchanal anastomosis era to have significant more complications and revisional surgery. The worldwide adoption of the pelvic pouch decreased the need for the continent ileostomy and a vicious circle evolved. Today only few centres perform the procedure. Patients who are not suitable for ileal anal-pouch anastomosis are seldom offered the possibility of having a continent ileostomy. Aims The aims of the study was to investigate surgical load, complications and long-term functional outcome and to define factors which affect these subjects in patients operated with ileal pouch-anal anastomosis, continent ileostomy or both in one single surgical department during the same period and without any institutional learning curve, and furthermore, to compare and contrast the two options. Material and methods From 1984 to 2005(7) 304 (315) patients were operated with IPAA at St. Olavs Hospital (earlier: Regional Hospital of Trondheim). From 1983 to 2002(7) 50 (65) patients had a continent ileostomy constructed. This was an observational study in the scope of surveillance and quality assurance. All patients were offered a planed regularly annual outpatient clinic follow up programme including a prospective standardised interview on clinical outcome. This was a supplement to clinical investigation with endoscopy and consecutive documentation of complications and other factors affecting the patients’ health. Data were recorded in the medical chart. In this system, all patients had recorded dataset. However, the intervals between data recordings differ and the intervals increased by time. All inpatients data were included. Standard descriptive statistical analysis and simple associations were undertaken. Handling longitudinal data with limited cases, varying time intervals was done in a Times Series Cross Sectional data model, analysed, and adjusted for several factors affecting functional outcome. Multivariable analysis was done. Results The estimated failure rate at 20 years was 11.4% for ileal pouch-anal anastomosis and 11.6% for continent ileostomy. Salvage procedures rates were 31% vs. 38%, respectively (p=0.06). The salvage procedures in IPAA included local procedures and redoes with laparotomy. Salvage procedures in CI were related to the function of the nipple valve, mainly nipple valve sliding and less frequent stenosis or fistulas. Complications rates were high. In pelvic pouch surgery, half of the patients would need re-operations in 20 years. Ten percentages had early anastomotic separation without septic complications. Four percentages had early pelvic septic complications. Fistulas and sepsis at the anastomotic site were the main severe complications, often leading to pouch failure. Closing of the loop ileostomy was accompanied with complications in six percentages. In the patients (48) who did not have a covering stoma the overall complications rate did not differ from those with a loop ileostomy, although nine needed a secondary stoma. Covering stoma seems to postpone anastomotic complications. Handsewn anastomosis had more strictures, but otherwise the complications rates were similar to stapled anastomosis. Patients having the diagnosis changed to Crohn`s diseases had more complications and higher failure rate. Early anastomotic complications were associated with long-term complications. In patients with continent ileostomy the nipple valve sliding is the main cause of revision. One third needed revision once or several times. At 20 years follow-up, half of the patients would need surgery due to complications. Although many patients with CI need several revisions, all patients were continent at the last follow up with a stable intubation frequency of 3 – 5 per 24 hour. The failure of the pelvic pouch is the end of severe complications. Two third of the failures had the pouch excision or permanent ileostomy with the pouch in situ. One third underwent a conversion to CI, with equal surgical and functional outcome as other patients with CI. In IPAA, bowel movements at day were between 5-6 at day and 0-1 at night. The rates of more or less frequent incontinence were about 10%, and 41% and 55% had reported soling at day and night respectively. The long-term functional outcome did not deteriorate with time: ie. observational time, as an independent factor did not influence outcome. Factors influencing the outcome were found but the impact of gender, age, protective stoma, hand-sewn anastomosis and early complications were negligible. Pouchitis did significantly influence functional outcome negatively, but did not create deterioration over time. Estimated pouchitis rate in IPAA was 43% for more than 20 years. The onset of the first pouchitis appears mostly in the 5-6 first years after surgery. The crude rate was 35% and 6% of the patients had chronic pouchitis. Severe/chronic pouchitis was associated with primary sclerosing cholangitis, but not with pyoderma gangrenousum or diagnosed joint affections. Idiopathic pouchitis were absent among patients with familial adenomatous polyposis. In continent ileostomy the rate of pouchitis was 26%. Conclusion The complications in both the pelvic pouch surgery and the surgery of continent ileostomy are considerable. Although not similar the surgical load are in the same order of magnitude. For the continent ileostomy revisional surgery are to be expected. The failure rate of both procedures are high and in long-term similar. The long-term functional outcome are however stabile and excellent. The failed pelvic pouch can be converted to a continent ileostomy in selected and motivated patients. The entity of pouchitis is conflicting and has to be divided into several different entities both on clinical, constitutional and other differentiating features. Patients with PSC should be informed of a possible higher risk of severe and chronic pouchitis after IPAA.

Chickpea production in the short growing season of the Canadian Prairies is still a challenging task due to excessive and continuous vegetative growth which often results in severe yield and quality reduction. This study examined the effects of three plant growth retardants (PGR), Chlormequat Chloride (CCC), Prohexadione Calcium and Trinexapac Ethyl applied during flowering stage on vegetative growth, seed quality, yield and crop maturity of the Kabuli chickpea cultivar CDC Frontier. Field experiments were conducted at Brooks and Bow Island in southern Alberta in the 2010 and 2011 growing seasons. Four concentrations of each PGR were applied at 10, 20 and 30 days after flowering (DAF) stages. During the 2010 growing season the crop experienced above average moist and cooler temperature conditions. In contrast, later half of the 2011 growing season was above average dry and hot. None of the three PGR tested in this study had a significant effect on plant height at 30 days after treatments or on above ground biomass plant-1 at harvest. Application of PGR had no significant effects on the number of seeds m-2, except at the Brooks rain-fed site in 2011 where the PGR treatment applied at 10 and 20 DAF increased the number of seeds m-2 at harvest. An increase of 1000-seed weight of marketable seeds was obtained with Prohexadione Calcium and Trinexapac Ethyl applications at Bow Island, but the effects were not consistent across sites and years. Results suggested that the effect of PGR on 1000-seed weight of marketable seeds mainly depended upon the growing environment and the type of PGR. In general, PGR applications reduced the total and marketable seed yields. Application of Prohexadione Calcium and Trinexapac Ethyl at the Bow Island site delayed crop maturity in 2011. In contrast, the application of CCC at 6000 mg L-1 at 20 DAF accelerated crop maturity at the Brooks irrigated site in 2011. In addition to this main study, the potential effects of Pyraclostrobin and Prothioconazole fungicides on the activities of the three PGR were compared by a separate experiment conducted at the Brooks irrigated site in 2011. The results of that study revealed that there were no significant differences in the effects of PGR on chickpea vegetative growth, seed yield parameters and maturity when they were applied as a mixture with either Pyraclostrobin or Prothioconazole fungicide. In summary, results revealed that PGR applied during flowering stage were not effective on controlling vegetative growth of chickpea and did not improve seed yield and crop maturity. Their effects on yield-related traits were highly inconsistent. Thus, it can be concluded that the application of PGR is not a reliable agronomic option to handle the production issues associated with continues vegetative growth at the late reproductive stage of the chickpea cultivar CDC Frontier under the western Canadian growing conditions.
