Mechanism and design of homogeneous heterobimetallic early metal-aluminum alkyl catalysts for ethylene trimerization and polymerization
Creators: name: Jabri, Amir
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2009
Subjects: subject: Chemistry, Organic.

description: This thesis describes an experimental study of the coordination chemistry of several early-metal based homogeneous catalysts for ethylene trimerization and polymerization. The first part of the thesis discusses a mechanistic study of chromium catalyzed ethylene trimerization and tetramerization based on the established NCy(PPh2)2 [PNP], NH(CH 2CH2SCy)2 [SNS], and pyrrole ligands. Through the isolation and characterization of catalytic resting states, many missing pieces to the mechanistic puzzle have been found, which aids the analysis of critical relationships between the chromium electronic state, geometry, nuclearity, and charge and the observed catalyst activity and selectivity. Some contributions include the first direct evidence for the involvement of Cr(I), Cr(II) and Cr(III) species in catalysis, 1-hexene selectivity enhancement via ligand-directed cocatalyst hemilability, and a well-defined single-component ethylene trimerization catalyst. The second part of the thesis explores olefin polymerization catalysis with pyrrole complexes of vanadium and titanium. The pyrrole ligand was found to enhance alkyl transfer between the transition metal and aluminum centres via its hemilability, which enhances the activation of normally kinetically inert metal electronic configurations. In addition, the alkyl shuttling allows the isolation of well-defined thermally stable complexes which form highly active single-site single-component polymerization catalysts at high temperatures.
Système d'idées et création de lois criminelles: Le cas de la loi contre la torture au Brésil

description: Cette recherche porte sur une étude de cas, à savoir la création de la loi contre la torture au Brésil, processus achève en 1997. L'intérêt que suscite ce processus vient de l'observation que le système politique, lors de la production de lois criminelles, actualise les mêmes idées sur les peines que celles actualisées par le système de justice criminelle. L'ensemble des ces idées va former, à partir du XVILle siècle, un "système" appelé par Alvaro Pires: la rationalité pénale moderne. Ce système d'idées communique, entre autres, une valorisation des peines d'exclusion sociale (prison) comme la seule réponse que l'État peut donner à certaines violations. À partir des documents et des entretiens réalisés auprès des politiciens et des militants des droits de la personne, la recherche explore en détail les étapes de la création de la loi: d'abord, la présentation du projet de loi qui a mis en branle tout le processus législatif conduisant à l'adoption de la loi actuelle contre la torture; ensuite, les discussions sur ledit projet de loi dans les commissions thématiques tant à la Chambre des députés qu'au Sénat et, enfin, les amendements suggérés par les députés et les sénateurs ainsi que les débats parlementaires dans les sessions plénières des deux Chambres. La recherche se penche aussi sur les réactions des médias et de la doctrine juridique à l'égard de la décision de créer ladite loi et sur la façon dont ces réactions stimulent ou imposent des limites à la reproduction des idées de la "rationalité pénale moderne" par le système politique. Il y a deux questions que cette recherche a explorées en particulier. La première concerne la définition de la position "politique" quant aux peines à partir de la distinction "conservateurs/progressistes". La deuxième a trait à la représentation par le système politique de la relation entre la sanction criminelle et la protection des droits de la personne. La recherche aborde les façons variées dont ce système conçoit le rôle du droit criminel et de la peine face aux droits de la personne et dans quel sens ces représentations peuvent "nourrir" la reproduction du même système répressif qui domine en Occident depuis presque deux siècles.

Variable-step variable-order 3-stage Hermite-Birkhoff ODE solver of order 5 to 15 with a C++ program

description: Variable-step variable-order 3-stage Hermite-Birkhoff (HB) methods HB( p)3 of order p = 5 to 15 are constructed for solving nonstiff differential equations. Forcing a Taylor expansion of the numerical solution to agree with an expansion of the true solution leads to multistep and Runge-Kutta type order conditions which are reorganized into linear confluent Vandermonde-type systems of HB type. Fast algorithms are developed for solving these systems in O(p2) operations to obtain HB interpolation polynomials in terms of generalized Lagrange basis functions. The order and stepsize of these methods are controlled by four local error estimators. These methods, when programmed in Matlab, are superior to Matlab's ode113 in solving several problems often used to test higher order ODE solvers on the basis of the number of steps, CPU time, and maximum global error. On the other hand, HB(5-15)3 are programmed in object-oriented C++ and the Dormand-Prince 13-stage nested Runge-Kutta pair DP(8,7)13M are programmed in C. DP(8,7) is found to use less CPU time, have smaller maximum global error but require a larger number of function evaluations than HB(5-15)3. However, for expensive equations, such as the Cubicwave, HB(5-15)3 is superior. In the C++ program, array and matrix are considered to be new objects. Algorithms, testing programs and new objects are structured separately as header files.

description: The effects of the Ohmic and magnetic density currents are investigated in the linearized Euler-Heisenberg electrodynamics. The linearization is introduced through an external magnetic field, in which the vector potential of the Euler-Heisenberg electrodynamics is expanded around of a magnetic background field, that we consider uniform and constant in this paper. From the Euler-Heisenberg linearized equations, we obtain the solutions for the refractive index associated with the electromagnetic wave superposition, when the current density is ruled by the Ohm law, and in the second case, when the current density is set by a isotropic magnetic conductivity. These solutions are functions of the magnetic background $({\bf B})$, of the wave propagation direction $({\bf k})$, it also depends on the conductivity, and on the wave frequency. As consequence, the dispersion and the absorption of plane waves change when ${\bf B}$ is parallel to ${\bf k}$ in relation to the case of ${\bf B}$ perpendicular to ${\bf k}$ in the medium. The characteristics of the refraction index related to directions of ${\bf B}$ and of the wave polarization open a discussion for the birefringence in this medium.

Analysis of formation control schemes for vehicles subject to kinematic constraints
Creators: name: Kepka, Maciek
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2005
Subjects: subject: Engineering, Mechanical.

description: This thesis focuses on control schemes for vehicle platoons. The study uses transfer function and Lyapunov function analysis, as well as computer simulations carried out to evaluate the performance of existing control schemes and to test the new control schemes proposed in this thesis. One of the results is a control algorithm that allows an indefinite number of followers to stay in formation behind a leader that follows a planar trajectory. In the design of this control scheme, the amount of information used by followers was minimized. Since the focus of the study is on the dynamics of a large formation of vehicles, individual vehicles were modeled in the simplest way possible: as point masses with a controlled acceleration vector applied to the point mass and subject to kinematic constraints. This thesis also presents further development of the string stability approach, extended from 1D (curvilinear) motion to 2D (planar) motion.

description: The “FAIR Implementation Workshop - Where do I start with FAIRification of sensitive data?” took place on 25th June at 14:00-15:15.

Sensitive data is ‘information that is regulated by law due to possible risk for plants, animals, individuals and/or communities and for public and private organisations’ (David et al, 2020). It is with these kinds of data in mind that the phrase “as open as possible and as closed as necessary” is now presented as part of the ‘Accessible’ principle of FAIR. There are many different types of sensitive data, and they exist in relation to many different contexts and disciplinary approaches. Perhaps most familiar to many will be personal data – for example, names collected during a survey or interview –  but there is also commercially sensitive information, data relating to the military or national security, and data about vulnerable species, and more.

This workshop presented a general overview of data sensitivity in relation to sharing and reuse; two presentations on aspects of sensitive data in different research areas; a focus on Persistent Identifiers and data handling of sensitive data; and an opportunity to join in the discussion with the presenters and with each other.

Symmetries, asymmetries and sense of direction

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2005
Subjects: subject: Computer Science.

description: This thesis deals with problems related to the notion of sense of direction in graphs: We define this notion and provide some examples of labelling that realize it. We then survey the problem of minimal sense of direction in regular graphs using symmetric labelling, and its connection to various notions such as cycle symmetry, vertex symmetry, Cayley graph, view, and surrounding. We also present new types of symmetries that are equivalent to having minimal sense of direction. Afterward, we cover the problem of minimal sense of direction in regular graphs using an asymmetric labelling and establish several new results regarding this problem. We show that many classical topologies do not have asymmetric minimal sense of direction using the asymmetric labelling. We conclude this thesis with a program that finds the minimum chordal labelling in an arbitrary graph.

description: The structure and intensity of turbulence in the atmospheric boundary layer (ABL) drives fluxes of sediment, contaminants, heat, moisture and CO$_2$ at the Earth's surface. Where ABL flows encounter changes in roughness -- such as cities, wind farms, forest canopies and landforms -- a new mesoscopic flow scale is introduced: the internal boundary layer (IBL), which represents a near-bed region of transient flow adjustment that develops over kilometers. This important scale lies within a gap in present observational capabilities of ABL flows, and simplified models fail to capture the sensitive dependence of turbulence on roughness geometry. Here we use large-eddy simulations, run over high-resolution topographic data and validated against field observations, to examine the structure of the ABL across a natural roughness transition: the emergent sand dunes at White Sands National Park. We observe that development of the IBL is triggered by the abrupt transition from smooth playa surface to dunes; however, continuous changes in the size and spacing of dunes over several kilometers influence the downwind patterns of boundary stress and near-bed turbulence. Coherent flow structures grow and merge over the entire $\sim$10-km distance of the dune field, and modulate the influence of large-scale atmospheric turbulence on the bed. Simulated boundary stresses in the developing IBL explain the observed downwind decrease in dune migration, demonstrating a mesoscale coupling between flow and form that governs landscape dynamics. More broadly, our findings demonstrate the importance of resolving both turbulence and realistic roughness for understanding fluid-boundary interactions in environmental flows.

Primary human fibroblasts are permissive for porcine cytomegalovirus in vitro

Year: 2007
Subjects: subject: Biology, Microbiology.

description: Xenotransplantation with pig organs is being considered to alleviate donor organ shortages; however, the risk of introducing porcine viruses to humans is exaggerated in this setting. Accordingly, the goal of this study was to determine the infectious potential of porcine cytomegalovirus (PCMV), a xenozoonotic virus of interest, in human fibroblasts in vitro. Confluent cells were incubated with either live PCMV or controls. Infection was investigated by light microscopy/neutral red staining, by RT-PCR and sequencing, and by Western blotting. Neutralization experiments were also performed. Cells incubated with PCMV demonstrated significant cytopathic effect by 7 days post-infection. Also, RT-PCR sequencing identified PCMV DNA polymerase in infected cells. In Western blots, monoclonal antibodies (mAbs) to human CMV glycoprotein B and pig serum presumed to contain anti-PCMV antibodies detected PCMV proteins by 19 days post-infection. Furthermore, one of these mAbs and the pig serum neutralized PCMV infection. Western blots and neutralization studies using a mAb to a human herpes virus 6 membrane glycoprotein provided no concrete evidence for a biological relationship between PCMV and human herpes virus 6. These results demonstrate that PCMV can infect human fibroblasts in vitro.

description: The thermal freeze-out mechanism in its classical form is tightly connected to physics beyond the Standard Model around the electroweak scale, which has been the target of enormous experimental efforts. In this work we study a dark matter model in which freeze-out is triggered by a strong first-order phase transition in a dark sector, and show that this phase transition must also happen close to the electroweak scale, i.e. in the temperature range relevant for gravitational wave searches with the LISA mission. Specifically, we consider the spontaneous breaking of a $U(1)^\prime$ gauge symmetry through the vacuum expectation value of a scalar field, which generates the mass of a fermionic dark matter candidate that subsequently annihilates into dark Higgs and gauge bosons. In this set-up the peak frequency of the gravitational wave background is tightly correlated with the dark matter relic abundance, and imposing the observed value for the latter implies that the former must lie in the milli-Hertz range. A peculiar feature of our set-up is that the dark sector is not necessarily in thermal equilibrium with the Standard Model during the phase transition, and hence the temperatures of the two sectors evolve independently. Nevertheless, the requirement that the universe does not enter an extended period of matter domination after the phase transition, which would strongly dilute any gravitational wave signal, places a lower bound on the portal coupling that governs the entropy transfer between the two sectors. As a result, the predictions for the peak frequency of gravitational waves in the LISA band are robust, while the amplitude can change depending on the initial dark sector temperature.

Mixed (Regular and Chaotic) Dynamics under the Channeling of the High Energy Positrons in [100] Direction of the Silicon Crystal and Podolskiy-Narimanov Distribution

description: The character of motion (regular or chaotic) on the quantum level manifests itself in the statistics of the set of the system's energy levels. The completely regular case generates the sequence of the levels with exponential (Poisson) level spacing distribution; the completely chaotic one -- with Wigner distribution. The most interesting case is the co-existence of the regular and chaotic motion domains in the phase space of the system under consideration. The assumption of independent generation of two level sequencies by one chaotic domain and by all regular domains leads to Berry--Robnik distribution. However, the presence of the chaotic motion domain in the phase space affects the levels produced by the regular domains via the so-called chaos-assisted tunneling (CAT) that leads to Podolskiy--Narimanov distribution of the level spacings. This distribution needs the mean amplitude of the tunnel transition and the relative contribution of the regular domains to the mean level density as the parameters. Using their estimations for the transverse motion of the high energy positrons channeling near [100] direction in the silicon crystal we found that Podolskiy--Narimanov distribution demonstrates the best agreement with the level spacing distribution.

The stress of subordinance: Socially mediated differences in acid-base regulation in rainbow trout (Oncorhynchus mykiss)
Creators: name: Mussa, Beidan
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2009
Subjects: subject: Biology, Animal Physiology.

description: Rainbow trout (Oncorhynchus mykiss) held in pairs engage in agonistic interactions resulting in one fish becoming dominant over the other, subordinate fish. Subordinate social status constitutes a chronic stress with subordinate fish exhibiting a prolonged elevation of circulating cortisol levels that in turn leads to reduced growth rates, altered metabolic function and compromised immune responses. The chronic stress experienced by subordinate fish also impacts ionoregulatory ability. Owing to the tight coupling between Na+ and Cl- uptake and, respectively, H + and HCO3- excretion at the gill, such ionoregulatory changes may affect acid-base regulation. Thus, the present study investigated the impact of social status on acid-base regulation of respiratory acidosis in rainbow trout. Responses of subordinate, dominant and control trout to 24 h of hypercapnia were compared. Social status appeared to impact net acid excretion (JnetH +) as subordinate individuals were unable to increase net acid flux in response to hypercapnia. However, despite this impaired response, blood acid-base status was found to be unaffected by social status before or during hypercapnic exposure, indicating that subordinate fish were as effective as dominant or control trout in achieving compensation for the acid-base disturbance. Compensation in all groups involved decreasing Cl- uptake in response to hypercapnia, thereby reducing HCO3- loss. Differences in branchial and renal Na+, K+-ATPase and H+-ATPase activities were documented between subordinate and dominant/control trout. Subordinate individuals exhibited elevated circulating cortisol concentrations prior to hypercapnia and failed to exhibit further increases in circulating cortisol levels in response to the acute stress of hypercapnia. Taken as a whole, the findings of this study suggest that subordinate fish are able to regulate body fluid pH during a respiratory acidosis, but this regulation may come at a greater cost than is the case in dominant or control fish.
Membrane Models as a Means of Propulsion in General Relativity: Super-Luminal Warp-Drive that Satisfies the Weak Energy Condition

Year: 2023

description: Presented are toy-models for sub-luminal and super-luminal warp-drives in 3+1 dimensions. The models are constructed in a chimeric manner - as different bulk space-times separated by thin membranes. The membranes contain perfect-fluid-like stress-energy tensors. The Israel junction conditions relate this stress-energy to a jump in extrinsic curvature across the brane, which in turn manifests as apparent acceleration in the bulk space-times. The acceleration on either side of the brane may be set individually by choice of model parameters. The Weak Energy Condition (WEC) is shown to be satisfied everywhere in both models. Although the branes in these toy models are not compact, it is demonstrated that super-luminal warp-drive is possible that satisfies the WEC. Additionally, the nature of these models provides framework for speculation on a mechanism for transition from sub-luminal to super-luminal warp. Neither quantum effects nor stability of the models is considered.

Prophétisme et autorité: une lecture politique du livre de Jonas

Subjects: subject: Political Science, General.

description: La présente thèse s'intéresse au rapport entre le prophétisme et le politique en se penchant sur le rôle du prophète dans la manifestation d'un phénomène politique précis : l'autorité. Dans cette optique, cette recherche vise à analyser le rapport particulier que le prophétisme entretient avec l'autorité dans le livre de Jonas, et ce, à partir de deux catégories tirées de la pensée du philosophe Serge Margel: le prophétisme abrahamique (l'autorité est tributaire d'une foi en la promesse d'un monde meilleur à venir) et le prophétisme mosaïque (l'autorité est tributaire d'une loi proposant un protocole pour faire advenir le monde meilleur promis). Cette étude conclut que le cas du prophète Jonas s'écarte des catégories proposées par Margel en les complexifiant. Plusieurs éléments du livre laissent croire que l'autorité du prophète Jonas ne repose ni sur la foi en un monde meilleur, ni sur une loi dictant une éthique pour faire advenir ce monde, mais sur l'expérience, par le prophète lui-même, " d'une seconde naissance ".
Harnessing intranet technology for organisational knowledge creation
Creators: name: Damsgaard, Jan

Publisher: name: Swinburne
Year: 2024

description: Many organisations have embraced intranets with the intent of harnessing the technology to support knowledge management initiatives. Despite the promise that intranet technology holds in this regard, many of the early research studies indicate rather disappointing results. In this paper we propose a model that organisations can use to conceptualise and reflect on their intranet applications with a view towards more fruitful results, specifically in terms of knowledge creation. We do so by drawing upon Nonaka's well-known framework of knowledge creation and combining that with a taxonomy of five intranet use modes. For each of Nonaka's four knowledge creating activities we associate and describe the corresponding primary intranet use mode that we argue can foster the knowledge creation process. We illustrate the arguments with findings from our own empirical intranet field studies and other documented intranet-related knowledge management research. We conclude with some implications of the model and we suggest avenues for further research.

description: The out-of-equilibrium character of active particles, responsible for accumulation at boundaries in confining domains, determines not-trivial effects when considering escape processes. Non-monotonous behavior of exit times with respect to tumbling rate (inverse of mean persistent time) appears, as a consequence of the competing processes of exploring the bulk and accumulate at boundaries. By using both 1D analytical results and 2D numerical simulations of run-and-tumble particles with different behaviours at boundaries, we scrutinize this very general phenomenon of active matter, evidencing the role of accumulation at walls for the existence of optimal tumbling rates for fast escapes.

A test of the relative and incremental predictive validity associated with a set of paper-and-pencil test measures and a set of situational test measures within an assessment centre.

description: A sample of two hundred and ninety-seven subjects from lower middle to upper middle levels of management within the Canadian Federal Government participated in an assessment centre program designed to facilitate the identification of potential for effective functioning at executive levels of management. During the assessment program, performance was assessed through a series of situational tests and a battery of psychometric paper-and-pencil tests. The general progression achieved by these participants approximately one and one-half to four years following assessment was evaluated by means of criterion measures related to position-level and salary, as well as a composite measure combining both of these criterion variables. The research was primarily designed to compare the predictive validity of a set of paper-and-pencil test measures with the validity associated with a set of situational test measures. As part of this effort, the research also focussed on the incremental validity which could ensue from the combination of both sets of predictors. The results of the investigation indicated that there was no significant difference in the amount of predictive variance accounted for by the paper-and-pencil versus situational testing methods. It was determined, however, that both sets of predictors added in an incremental fashion in the overall prediction of progression within the organization. The existence of this relationship was to some extent dependent upon the criterion measure considered.

Afin de mieux connaître l'importance de ces facteurs et de leurs relations avec les symptômes dépressifs et avec l'usage de substances (cigarette, alcool et cannabis), le sondage CTC-YS (Communities That Care-Youth Survey) a été administré en 2006 et 2007 dans deux régions de l'Ontario auprès de 4 600 élèves de la sixième à la douzieme année fréquentant les écoles anglaises et françaises. Cette première exploration en contexte bilingue de 23 facteurs de risque et 11 facteurs de protection et de leurs relations avec les symptômes dépressifs, le tabagisme, la consommation d'alcool et l'usage de cannabis montre des différences, quoique modestes, entre les élèves des écoles anglaises et françaises. Dans les deux échantillons, les élèves des écoles anglaises avaient des niveaux plus élevés de facteurs de risque et de symptômes dépressifs que ceux des ecoles francaises, et des niveaux plus faibles sur plusieurs facteurs de protection. Cependant, les relations individuelles entre ces facteurs et les problèmes s'équivalaient pour les deux groupes. Les symptômes dépressifs et leurs relations avec une grande majorité de facteurs de risque s'avéraient plus élevés chez les filles que chez les garçons. En contrepartie, les facteurs de protection, dans les domaines de la famille, de l'école et des pairs, les avantageaient. Les adolescents plus jeunes semblaient plus vulnérables à l'usage de substances que les adolescents plus âgés, certaines relations avec les facteurs de risque étant plus marquées, mais les facteurs de protection dans les domaines de la famille et des pairs jouaient en leur faveur. La discussion porte sur la pertinence de l'utilisation du sondage CTC-YS en milieu ontarien bilingue pour la prévention de difficultés comportementales et de santé mentale, et sur l'importance d'offrir des interventions multidimensionnelles favorisant à la fois l'augmentation des facteurs de protection et la'diminution des facteurs de risque dans les divers milieux de vie des jeunes.

description: The phylogeny of land plants, especially angiosperms, has been perplexing scientists for more than 125 years. The aim of this study was to help elucidate unanswered phylogenetic issues using rpb1 genes from twenty-six land plant species (8 gymnosperm species, 17 angiosperm species and Psilotum, a fernally, as the outgroup). The sixteen rpb1 genes which were sequenced in this study had very similar lengths and contained no base compositional bias. Synonymous substitutions of rpb1 sequences were saturated when compared to the outgroup. The third codon positions of these genes contained misleading phylogenetic information. The topology of trees based on first and second codon positions were in line with that of protein trees. Both angiosperms and gymnosperms were monophyletic. Amborella was found at the base of the angiosperm tree, followed by Nymphae, then Illicium. These data rejected the anthophyte hypothesis, weakly supported the gnepine hypothesis, but did not resolve the interrelationship among eumagnoliids and eudicots. rpb1 genes were combined with the 18S ribosomal RNA gene and chloroplast atpB and rbcL genes to obtain more robust phylogenies. This combined data set produced a topology similar to that of the first and second positions of rpb1 genes except that they better resolved the interrelationship among eumagnoliids and eudicots. We conclude that our rpb1 sequences evolve too slowly to provide enough phylogenetic information to fully resolve the phylogeny of seed plants and that other gene sequences will need to be added to these data sets to obtain a well-resolved phylogenetic tree of seed plants.

Thermal quality influences thermoregulation, behaviour and habitat selection at multiple scales in eastern milksnakes (Lampropeltis triangulum)

description: Body temperature variation affects most physiological processes in terrestrial ectotherms and, therefore, can have a large effect on fitness. I studied eastern milksnakes at the northern extreme of their range, in a thermally challenging environment. Because of the particular importance of thermoregulation in thermal extremes, I hypothesized that thermal quality would influence thermoregulation, behaviour and habitat selection. In chapter one, I demonstrated that when thermal quality decreased, milksnakes increased investment in thermoregulation, a result contrary to the central prediction of the cost-benefit model of thermoregulation. Because ecotherms obtain heat from their environment, I predicted that when thermal quality was low, milksnakes would bask more and select higher thermal habitat. Milksnakes did not alter their habitat use in response to thermal quality. They did, however, alter their behaviour and were seen basking more and concealed less when thermal quality was low. In chapter two, my main goal was to determine if thermal quality affected habitat selection at multiple scales. Supporting my prediction, thermal quality influenced habitat selection at both the home range scale and the location scale. At both scales, milksnakes selected high thermal quality habitats (rocky outcrops, fields, and edges) and avoided low thermal quality habitat (forest). At the microhabitat scale, milksnakes selected locations with open canopy and many rocks. As a secondary objective, I tested the ability of 4 m resolution IKONOS imagery to accurately quantify habitat selection at the scale of the locations used by each snake. Although not as accurate as traditional field methods, remote sensing showed promise in measuring habitat selection at that scale.

Subjects: subject: Health Sciences, Nursing.

description: Background. Several theoretical models now suggest the need to promote an organizational approach to practice change for nursing. Objectives. To examine organizational factors that influence revisions and modifications to policies and procedures in health care agencies that participated in a pilot implementation and evaluation of six clinical practice guidelines developed by the Registered Nurses Association of Ontario. To describe the nature and extent of changes to policies and procedures from the perspective of nursing administrators, clinical resource nurses and nursing staff. Conclusion. Organizational support in the form of perceived support by top management, sufficient time and training to learn how to use the clinical guideline, adequate number of qualified staff and sufficient equipment and supplies to implement the clinical guideline is important and can influence nurses' awareness of evidence-based modification of policies and procedures. Further research is needed to compare nurses' actual practice with current policies and procedures. In addition, research is needed to determine whether organizations that modified or internalized their policies and procedures sustained the implementation of the clinical guidelines recommendations better over time.

Ecology, biological characterization and development of an animal model for Enterobacter sakazakii

description: Enterobacter sakazakii is an emerging foodborne pathogen which has been linked to a number of outbreaks associated with the consumption of powdered infant formula, especially in low-birth-weight and premature infants. Very little research has focused on molecular characterization of this organism and the mechanism(s) by which it causes disease in humans. In this study, a collection of 260 isolates of E. sakazakii were assessed by phenotypic and genotypic tests. The use of 16S rDNA analysis showed an 82% identity amongst the strains tested. Interestingly, 14 strains originally identified as E. sakazakii by phenotypic characterization, were found to be other species or genera. Among the molecular typing methods, pulsed-field gel electrophoresis was found to be more discriminatory than automated ribotyping. Furthermore, the theory that expressed human breast milk, if contaminated with E. sakazakii, would support E. sakazakii growth at 10, 23 and 37°C, was investigated. It was found that the intrinsically ascribed antimicrobial properties of breast milk do not appear to inhibit the growth of this foodborne pathogen in vitro. Lastly, we assessed six animal species to find an animal model that would be well suited to conduct further studies on the virulence of E. sakazakii infection. Young (chicks, gerbils, guinea pigs, pigs, rabbits) and neonatal (gerbils, rats) animals were orally challenged with E. sakazakii at a level of 109 cells. Of all the animal models tested, it appears that the neonatal gerbil may be most suitable for further studies.

description: A SQUID magnetometer has been used to study the N.M.R. signal and the relaxation time of normal aluminum in low magnetic fields as a function of temperature for the purpose of doing thermometry below 1K. The variation of signal amplitude with temperatures and r.f. power is found to agree with the predictions from the Bloch equations. A description is given of the cryostat that used a circulating helium gas heat exchanger to cool the experimental stage to 1.3K and adiabatic demagnetization of a paramagnetic salt to further cool the stage to 240 mK. The N.M.R. spectrum of lithium in a crystal of lithium niobate was also studied at 4.2K. The quadrupole coupling constant e2qQ/h was measured to be 52 +/- 1 KHz and is compared to previous results. The design of a new cryostat to operate below 100 mK to replace the current one in use is discussed. The construction and operation of a liquid helium level indicator is discussed and commented on.
