The microorganism with the highest percentage of reports 91 (36,7%) was Acinetobacter baumanii, it also related to cases of PAV and ICS, while Candida albicans (8.5%) appears as the most frequent microorganism in cases of UTI. 267 individuals (43.6%) presented IRAS, of which 49 (55.8%) resulted from invasive device infections. Regarding deaths during the same period, 179 individuals (29.2%) of the total hospitalizations died, of which 74 death (41.3%), was related/caused by infections. Comparing the two moments, no significant association was observed among the individuals who presented hospital infection, the total number of infections by invasive devices and deaths related/caused by infections, that is, the incidence of IRAS, did not decrease after the use of the protocol, but when analyzing the types of infection separately, it was evidenced that the use of Bundles was effective for the prevention of PAV and ICS in burns.

Manifolds, Vector Bundles, and Stiefel-Whitney Classes

Green, Michael Douglas, 1965- 08 1900 (has links)
The problem of embedding a manifold in Euclidean space is considered. Manifolds are introduced in Chapter I along with other basic definitions and examples. Chapter II contains a proof of the Regular Value Theorem along with the "Easy" Whitney Embedding Theorem. In Chapter III, vector bundles are introduced and some of their properties are discussed. Chapter IV introduces the Stiefel-Whitney classes and the four properties that characterize them. Finally, in Chapter V, the Stiefel-Whitney classes are used to produce a lower bound on the dimension of Euclidean space that is needed to embed real projective space.

Spectral data for G-Higgs bundles

Schaposnik, Laura P. January 2013 (has links)
We develop a new geometric method of understanding principal G-Higgs bundles through their spectral data, for G a real form of a complex Lie group. In particular, we consider the case of G a split real form, as well as G = SL(2,R), U(p,p), SU(p,p), and Sp(2p,2p). Further, we give some applications of our results, and discuss open questions.

Autoduality of the Hitchin system and the geometric Langlands programme

Groechenig, Michael January 2013 (has links)
This thesis is concerned with the study of the geometry and derived categories associated to the moduli problems of local systems and Higgs bundles in positive characteristic. As a cornerstone of our investigation, we establish a local system analogue of the BNR correspondence for Higgs bundles. This result (Proposition 4.3.1) relates flat connections to certain modules of an Azumaya algebra on the family of spectral curves. We prove properness over the semistable locus of the Hitchin map for local systems introduced by Laszlo–Pauly (Theorem 4.4.1). Moreover, we show that with respect to this Hitchin map, the moduli stack of local systems is étale locally equivalent to the moduli stack of Higgs bundles (Theorem 4.6.3) (with or without stability conditions). Subsequently, we study two-dimensional examples of moduli spaces of parabolic Higgs bundles and local systems (Theorem 5.2.1), given by equivariant Hilbert schemes of cotangent bundles of elliptic curves. Furthermore, the Hilbert schemes of points of these surfaces are equivalent to moduli spaces of parabolic Higgs bundles, respectively local systems (Theorem 5.3.1). The proof for local systems in positive characteristic relies on the properness results for the Hitchin fibration established earlier. The Autoduality Conjecture of Donagi–Pantev follows from Bridgeland–King–Reid’s McKay equivalence in these examples. The last chapter of this thesis is concerned with the con- struction of derived equivalences, resembling a Geometric Langlands Correspondence in positive characteristic, generalizing work of Bezrukavnikov–Braverman. Away from finitely many primes, we show that over the locus of integral spectral curves, the derived category of coherent sheaves on the stack of local systems is equivalent to a derived category of coherent D-modules on the stack of vector bundles. We conclude by establishing the Hecke eigenproperty of Arinkin’s autoduality and thereby of the Geometric Langlands equivalence in positive characteristic.

Disseminating the Sepsis Bundle: Evaluating an Evidence-Based Education Module

Isopo, Elyse Diana 01 January 2018 (has links)
Due to increasing incidence and noncompliance with sepsis at a local hospital, an educational deficit was identified on the sepsis bundle in the medical intensive care unit. The purpose of this project was to develop and validate a sepsis bundle education program for all frontline staff in the MICU at a local University Hospital. The goal was for the educational tool to be validated by a multidisciplinary team to increase awareness, education, and ultimately, compliance with the severe sepsis and septic shock guidelines. The diffusion of innovation theory was utilized to support the process of change by encouraging the use of screening tools and best practice guidelines. The research question asked whether the education program meets critical care expert panel standards to educate frontline MICU staff on the sepsis bundle. The research design included a 5-member panel of experts in critical care, utilizing the Likert scale to review the proposed educational project on the sepsis bundle. Results are averaged from each reviewer. Results from the review included a unanimous '5' rating on every issue identified, equating to strongly agree on the Likert scale. This rating supported the validity of the educational project, the use of evidence-based practice and that the educational material was clear and easy to follow. Utilizing this validated tool will guide the education of sepsis, severe sepsis, and septic shock and promote social change by increasing education, awareness, recognition and early deployment of the sepsis bundle to improve patient outcomes.

Development of two-frequency planar doppler velocimetry instrumentation

Charrett, Thomas O. H. January 2006 (has links)
Engineering and Physical Science Research Council (EPSRC) / This thesis describes the development of the two-frequency Planar Doppler Velocimetry (2n-PDV) flow measurement technique. This is modification of the Planar Doppler Velocimetry (PDV) technique that allows the measurement of up to three components of the flow velocity across a plane defined by a laser light sheet. The 2n-PDV technique reduces the number of components required to a single CCD camera and iodine cell from the two CCDs in conventional PDV. This removes the error sources associated with the misalignment of the two camera images and polarisation effects due to the beam splitters used in conventional PDV. The construction of a single velocity component 2n-PDV system is described and measurements made on the velocity field of a rotating disc and an axisymmetric air jet. The system was then modified to make 3D velocity measurements using coherent imaging fibre bundles to port multiple views to a single detector head. A method of approximately doubling the sensitivity of the technique was demonstrated using the measurements made on the velocity field of the rotating disc and was shown to reduce the error level in the final orthogonal velocity components by ~40 to 50%. Error levels of between 1.5ms-1 and 3.1ms-1 depending upon observation direction are demonstrated for a velocity field of ±34ms-1. The factors that will influence the selection of a viewing configuration when making 3D PDV measurements are then investigated with the aid of a computer model. The influence of the observation direction, the magnitude of the flow velocity, and the transformation to orthogonal velocity components are discussed. A new method using additional data in this transformation is presented and experimental results calculated using four-measured velocity components are compared to those found conventionally, using only three components. The inclusion of additional data is shown to reduce the final error levels by up to 25%.
