Conducting polymers that contain metals are remarkable materials, because they have the properties of both organic backbones and metals. Depending on the position of the metal relative to the conjugated backbone, i.e. attached to or directly in the backbone, these two can couple resulting in advancement of the functionality and therefore potential applications of these types of materials. Complexes of tridentate ligands with donor atoms such as phosphorus, nitrogen, and sulfur also have a wide variety of applications. In addition, complexes of tridentate ligands have advantages of stability and control of electron density by variation of donor atoms. Therefore, conjugated polymers with tridentate ligand units will have promise for various applications and advantages in their designs. Complexes of PNP ligand with molybdenum and carbonyl ancillary ligands were synthesized and characterized. Isomerization and conversion reactions between them were investigated as well as the coordination modes. Many types of PNP ligands have been studied in the literature because the hemilabile property of the nitrogen atom promotes some catalytic reactions and gives different coordination geometries. Conducting polymers can be used as redox-active ligands and they can be used to control electron density on the metal attached to them. Synthesis and characterization of a novel polymerizable ligand 3,5-bis-EDOT-N,N-bis[2-diphenylphosphinoethyl]aniline was achieved. Related molybdenum complexes with ancillary ligands as carbonyls were also synthesized and characterized. Monomer complexes and the free ligand were electropolymerized and studied. Tris(bipyridine)ruthenium(II) chloride and analogous complexes have been studied extensively in the literature due to their luminescent and photochemical properties, and excited state lifetimes. Conducting polymers with similar ruthenium groups have been investigated for various applications. Synthesis of four ruthenium complexes with the polymerizable ligand 2,6-Bis[4-[2-(3,4-diethylenedioxy)thiophene]pyrazol-1-yl]pyridine and four different bidentate ligands were reproduced; electropolymerizations of the complexes were achieved; electrochemical, UV-Vis and luminescence studies were performed and discussed. Various complexes of copper, silver, platinum, and palladium with nitrogen and phosphorus donors have been reported for their luminescence behavior as well as their interesting structures. Model complexes of these metals with N,N-bis[2-(diphenylphosphino)ethyl]phenyl-amine (a PNP ligand) have been synthesized and characterized. Absorption and luminescence behaviors as well as the coordination modes were investigated. / text

INTRODUÇÃO: A legislação em enfermagem prevê o uso da Sistematização da Assistência de Enfermagem (SAE). As atitudes dos profissionais de enfermagem sobre o processo de enfermagem (PE) e o poder clínico que percebem ter para realizar mudanças são fatores potencialmente associados ao processo de implantação e manutenção da SAE. OBJETIVOS: Descrever as atitudes relacionadas ao PE (disposição sobre o PE e percepção de poder clínico) de auxiliares de enfermagem e enfermeiros; analisar associações entre atitudes relacionadas ao processo de enfermagem e variáveis selecionadas. MÉTODO: Estudo descritivo-exploratório de delineamento transversal, com amostra não probabilística de 973 auxiliares de enfermagem e 632 enfermeiros de 35 hospitais e ambulatórios vinculados à Secretaria de Estado da Saúde de São Paulo (86,9% do sexo feminino, idade média de 44,12 anos (DP= 9,55), 52,3% trabalhavam em hospitais gerais, cerca de 44 horas semanais, estavam nas instituições há 10 anos em média). Os dados foram coletados por meio de resposta ao instrumento de caracterização sociodemográfica e aos questionários padronizados Posições sobre o Processo de Enfermagem (PPE) adaptado para esse estudo e o Power as Knowing Participation in Change Tool- versão brasileira (PKPCT), que apresentaram boas estimativas de validade e confiabilidade. Testes não paramétricos foram usados para analisar associação entre as atitudes relacionadas ao PE e as variáveis selecionadas. RESULTADOS: O escore total médio no PPE foi de 112,37 (DP=22,28) e o escore total médio no PKPCT foi de 281,12 (DP= 38,72) para os 1605 respondentes. Houve associação entre as duas atitudes relacionadas ao PE e categoria profissional, a atitude dos enfermeiros sobre o PE foi mais favorável que a dos auxiliares de enfermagem (p=0,024) e a percepção de poder dos enfermeiros foi mais elevada que a dos auxiliares de enfermagem (p=0,004). Houve correlação positiva moderada entre os escores do PPE e do PKPCT para os auxiliares (r=0,480; p=0,000) e para os enfermeiros (r=0,460; p=0,000). Os auxiliares do sexo feminino tiveram disposição sobre o PE (111,93) mais favorável que os do sexo masculino (106,11) (p=0,018) e maior percepção de poder (279,75 vs 270,84) (p=0,020); na amostra de enfermeiros não houve associação entre essas variáveis. Apenas para os auxiliares de enfermagem ter pós-graduação associou-se significativamente a maiores médias de atitude sobre o PE (119,0, p=0,011). As enfermeiras que relataram ter cargo de chefia apresentaram escores de percepção de poder mais elevados (293,52) que as enfermeiras sem cargo de chefia (282,61 p=0,010), mas não houve associação entre cargo de chefia e atitude sobre o PE. As associações entre os escores do PPE e PKPCT e as variáveis idade, tempo de formado, atividade principal, satisfação com a carreira, satisfação com o local de trabalho, conhecimento e contato com a SAE foram de intensidade desprezível no caso das correlações ou não significantes ao nível de 5%. / INTRODUCTION: The Brazilian nursing legislation requires that the nursing process (NP) is documented in all health institution. Attitudes of nursing staff towards the nursing process (NP) and their perception on their own clinical power to make changes are factors potentially associated with implementation and maintenance of the NP. OBJECTIVES: To describe the attitudes towards NP (attitudes on NP and perception of clinical power) of auxiliary nurses and baccalaureate nurses; and to analyze associations between attitudes towards the NP and selected variables. METHODS: An exploratory descriptive study with cross-sectional design, with a non-probabilistic sample of 973 auxiliary nurses and 632 baccalaureate nurses from 35 health agencies linked to the Ministry of Health of São Paulo, Brazil (86.9% female, mean age = 44.12 years (SD = 9.55), 52.3% worked in general hospitals, about 44 hours per week, were in institutions for 10 years on average). Data were collected by self-report using a form for personal, educational and other social data, and the Positions on Nursing Process (PNP) tool, adapted for this study, and the Power as Knowing Participation in Change Tool-Brazilian version (PKPCT), which showed good estimates of validity and reliability. Nonparametric tests were used to test associations between attitudes towards the NP and the selected variables. RESULTS: The mean PNP total score was 112.37 (SD = 22.28) (possible range = 20-140) and the mean PKPCT total score was 281.12 (SD = 38.72) (possible range = 48-336) for 1605 subjects. There was an association between the two PNP-related attitudes and professional category; the attitude of baccalaureate nurses on the NP was more favorable than that of auxiliary nursing (p = 0.024) and perceived clinical power of the baccalaureate nurses was higher than that of the auxiliary nurses (p = 0.004). There was moderate positive correlation between the scores of the PNP and PKPCT for auxiliary nurses (r = 0,480, p = 0.000) and baccalaureate nurses (r = 0.460, p = 0.000). The female auxiliary nurses had higher scores on PNP (111.93vs 106.11; p = 0.018) and PKPCT (279.75vs. 270.84; p = 0.020) than the male ones. There were no associations between sex an attitudes towards NP among baccalaureate nurses. Only for auxiliary nurses sample attending a continuing education program was associated with higher NP scores (119.0, p = 0.011). Baccalaureate nurses serving in leadership positions had higher mean total score on PKPCT (293.52) than nurses serving in direct care (282.61 p = 0.010), but there was no association between leadership position and PNP scores. Association tests for scores of the PNP and PKPCT and the variables age, time since graduation, main activity, satisfaction with the career, satisfaction with the workplace, knowledge on NP and contact with the NP resulted in negligible correlation coefficients or non-significant coefficients at 5%.

La contamination de plusieurs poches de nutrition parentérale (PNP) par une bactérie inconnue, a déclenché une investigation, toujours en cours. Les objectifs essentiels étaient de caractériser cette bactérie sur le plan taxonomique pour permettre de la reconnaître dans d'autres contextes. Le séquençage du gène rrs, codant l'ARN 16S, a permis de positionner la bactérie inconnue parmi les Enterobacteriaceae, à proximité des genres Ewingella, Rahnella, Serratia, Yersinia et Hafnia. Le séquençage du génome total de la bactérie a permis d'utiliser cinq gènes pour une étude MLSA (multi-locus sequence analysis). L'arbre phylogénétique ainsi obtenu montre que la bactérie (six isolats ne représentant qu'une seule souche) représente un nouveau genre de la famille Enterobacteriaceae que nous avons appelé Rouxiella, l'espèce étant Rouxiella chamberiensis. Un des isolats a été désigné souche-type et déposé dans les collections dans deux pays différents (CIP, France et DSMZ, Allemagne). Les propriétés physiologiques et biochimiques de R. chamberiensis ont permis d'en faire une description. R. chamberiensis ne se développe pas à 37 °C, ce qui ne plaide pas pour une action pathogène active sur l'homme, ne produit pas de nitrate réductase (au contraire de la très grande majorité des Enterobacteriaceae, mais comme Erwinia), et ne fermente que peu de glucides. Le nom Rouxiella chamberiensis a été validé par publication dans l'International Journal of Systematic and Evolutionary Microbiology. Dès que ce nouveau genre et espèce a été publié, d'autres chercheurs ont isolé de l'environnement des souches qui étaient proches de Rouxiella. Une collaboration avec une équipe allemande a permis de décrire deux nouvelles espèces de Rouxiella, « R. badensis » et « R. sylvae » / The contamination of several parenteral nutrition bags (PNB) with unknown bacterium started an investigation, which is still ongoing. The essential objectives were: to characterize this bacterium taxonomically to allow to recognize it in others contexts. Sequencing the rrs gene (encoding 16S rRNA) allowed to position the unknown bacterium in the family Enteriobacteriaceae, close to genera Ewingella, Rahnella, Serratia, Yersinia and Hafnia. Whole genome sequencing was done. Five genes were used for a MLSA (multi-locus sequence analysis) study. The MLSA phylogenetic tree showed the bacterium (six isolates were only one strain) to represent a new genus of the family Enteriobacteriaceae, named Rouxiella, the species being Rouxiella chamberiensis. One isolate have been designated as the type strain and deposited in two collections in two different countries (CIP, France and DSMZ, Germany). The physical and biochemical properties of R. chamberiensis were used in a formal species description. R. chamberiensis failed to grow at 37 °C, this does not plead for a pathogenic action for human, negative results in tests for reduction of nitrate (which is rare in the Enterobacteriaceae, excepted Erwinia), and fermented a few carbohydrates. The name Rouxiella chamberiensis has been approved by publication in International Journal of Systematic and Evolutionary Microbiology. When this new genus and species has been published, other researchers have isolated environmental strains close to Rouxiella chamberiensis. Collaboration with a German team allowed us to describe two new species of Rouxiella, "R. badensis" and "R. sylvae"

A series of tetravalent zirconium and hafnium complexes were developed in their abundant chemistry and photophysical properties, where those complexes were supported by diarylamido-phosphino [iPr-PNP]- (bis(o-diisopropylphosphinophenyl)amide) ligand. [iPr-PNP]MCl3 (M = Zr, Hf) were prepared by sequentially reacting [iPr-PNP]H with n-butyllithium and following MCl4(THF)2 in toluene solution under ambient temperature. UV-Vis absorption, emission, excitation spectrum, cyclic voltammetry experiments, and density functionalization theory (DFT) calculations are applied to approach their unique photophysical phosphorescence properties. Alkyls which are lack of £]-hydrogen have been used to achieve in synthesis of degenerate ([iPr-PNP]MR3, R = Me, CH2SiMe3) or non-degenerate ([iPr-PNP]M(E)(R)2, R = CH2SiMe3, E = Cl, Me) derivatives since we could control the desired product from steric effect. Strong fluxional exchange was found in those complexes. By variable temperature NMR monitoring and X-ray diffraction, their fluxionality seems interesting not only in mechanism, but it does affect our reaction. By heating [iPr-PNP]Zr(Cl)(CH2SiMe3)2 in solution, we can afford new alkylidene complexes [iPr-PNP]M(Cl)(=CHSiMe3) via self £\-abstraction. Through variable temperature analysis, the activation energy of £\-abstraction have £GH‡ = 18.5 kcal/mol and £GS‡ = -19.8 cal/mol¡PK. Here we also can identified multiple alkylidene derivatives of [iPr-PNP]Zr(Me)(=CHSiMe3)2. The computational studies of [MeNPiPr]Ni(R)(L) ([MeNPiPr]- = o-diisopropylphosphinoII phenyl-2,6-dimethylanilite, R = Me, CH2SiMe3; L = 2,4-Lutidine, Py, PMe3) in C-H activation has been fully established. Start on dissociation mechanism, we considered three major pathways to explain the activation mechanisms including isomerisation, direct intermolecular benzene activation, and intramolecular sp3 C-H acitvaition. Here we also account H-D exchange as experimental observation. Important intermediates and transition states are found to locate the energy maps to assist our experiments.

This thesis considers the Perspective-N-Point (PNP) problem with orthogonal target geometry, as seen in the problem of cubesat relative navigation. Cubesats are small spacecraft often developed for research purposes and to perform missions in space at low cost. Sensor systems for cubesats have been designed that, by providing vector (equivalently line-of-sight, angle, and image plane) measurements, equate relative navigation to a PNP problem. Much study has been done on this problem, but little of it has considered the case where target geometry is known in advance, as is the case with cooperating cubesats. A typical constraint for cubesats, as well as other PNP applications, is processing resources. Therefore, we considered the ability to reduce processing burden of the PNP solution by taking advantage of the known target geometry. We did this by considering a specific P3P solver and a specific point-cloud correspondence (PCC) solver for disambiguating/improving the estimate, and modifying them both to take into account a known orthogonal geometry. The P3P solver was the Kneip solver, and the point-cloud-correspondence solver was the Optimal Linear Attitude Estimator (OLAE). We were able to achieve over 40% reduction in the computational time of the P3P solver, and around 10% for the PCC solver, vs. the unmodified solvers acting on the same problems. It is possible that the Kneip P3P solver was particularly well suited to this approach. Nevertheless, these findings suggest similar investigation may be worthwhile for other PNP solvers, if (1) processing resources are scarce, and (2) target geometry can be known in advance.

abstract: A modeling platform for predicting total ionizing dose (TID) and dose rate response of commercial commercial-off-the-shelf (COTS) linear bipolar circuits and technologies is introduced. Tasks associated with the modeling platform involve the development of model to predict the excess current response in a bipolar transistor given inputs of interface (NIT) and oxide defects (NOT) which are caused by ionizing radiation exposure. Existing models that attempt to predict this excess base current response are derived and discussed in detail. An improved model is proposed which modifies the existing model and incorporates the impact of charged interface trap defects on radiation-induced excess base current. The improved accuracy of the new model in predicting excess base current response in lateral PNP (LPNP) is then verified with Technology Computer Aided Design (TCAD) simulations. Finally, experimental data and compared with the improved and existing model calculations. / Dissertation/Thesis / Masters Thesis Electrical Engineering 2017

A alta susceptibilidade dos infectados por HIV para a tuberculose, bem como a proliferação da tuberculose multidroga-resistente (MDR), tem criado um grande interesse mundial de expansão nos programas atuais de pesquisas sobre a tuberculose. A Purina Nucleosídeo Fosforilase do Mycobacterium tuberculosis (MtPNP) é um potencial alvo para novas drogas anti-tuberculose visto que é responsável pela síntese de novo de ribonucleotídeos de purina. A Inibição específica da PNP poderia potencialmente levar o M. tuberculosis ao estado latente. O objetivo desde trabalho é resolver a estrutura da MtPNP complexada com adenina, e analisar as interações com os ligantes. A MtPNP foi cristalizada utilizando condições experimentais descritas posteriormente, e o ligante (adenina) foi adicionado por soaking. Os dados de difração de raios X foram coletados no detector CCD utilizando fonte de radiação síncotron (Laboratório Nacional de Luz Síncrotron, LNLS, Campinas, Brazil). O programa MOSFLM foi utilizado para o processamento, e os dados foram escalonados através do programa SCALA, apresentando o grupo espacial ortorrômico P21212 (a=118,96Å, b=134,65 Å, c=44,42 Å).

The high susceptibility of human immunodeficiency virus infected persons to the disease and the proliferation of multidrug-resistant (MDR) strains have created a worldwide interest in expanding current programs in tuberculosis research. The Purine Nucleoside Phosphorylase from Mycobacterum tuberculosis (MtPNP) is a potential target for new drug anti-tuberculosis, whereas is responsible for de novo synthesis of purine ribonucleotides. The specific inhibition of M. tuberculosis PNP could potentially lead to the latent state of M. tuberculosis. The objective of this work is to solve the structure from MtPNP complexed with adenine, and to analyze their interactions with the ligand. MtPNP was crystallized using the experimental conditions described elsewhere, and the ligand (adenine) was added by soaking. The X-ray diffraction data were collected on a CCD detector using synchrotron radiation source (Laboratório Nacional de Luz Síncrotron, LNLS, Campinas, Brazil).
