Abstract:
Two novel europium(III) complexes, a monomer and a homodimer, with 1-(4-chlorophenyl)-4,4,4-trifluoro-1,3-butanedione (Hcbtfa) and 5-chloro-1,10-phenanthroline (cphen) ligands, formulated as [Eu(cbtfa)3(cphen)] and [Eu2(cbtfa)4(cphen)2(CH3O)2], have been synthesized. Their structures have been elucidated by X-ray diffraction and their absorption and emission properties have been studied in the solid state. The experimental data has then been used to test the recently released LUMPAC software, a promising tool which can facilitate the design of more efficient lanthanide light-conversion molecular devices by combining ground state geometry, excited state energy, and luminescent properties calculations.

Abstract:
Adolescent idiopathic scoliosis Lenke I dengan pola kurva mayor pada kurva thorakal (main thoracic), dengan kurva proximal thoracic dan thoracolumbar/lumbar sebagai kurva minor non struktural. Instrumentasi dan fusi hanya pada kurva thorakal dianjurkan. Pada literatur dijelaskan bahwa koreksi spontan kurva lumbal terjadi sebagai kompensasi untuk menyeimbangkan kurva thorakal setelah dilakukannya fusi thorakal selektif. Lumbal modifier dibagi menjadi 3 grup, pemilihan terapi operatif bergantung pada tipe lumbal modifier. Penelitian ini merupakan suatu analisis observational pada 35 pasien adolescent idiopathic scoliosis Lenke I paska operasi koreksi deformitas dan instrumentasi posterior. evaluasi menggunakan X ray sebelum dan setelah operasi untuk penentuan tipe lumbal modifier, besarnya koreksi kurva thorakal dan penilaian koreksi spontan kurva lumbal, kemudian dilakukan uji korelasi terhadap data yang didapat. Besarnya koreksi kurva thorakal terhadap koreksi spontan kurva lumbal paska operasi memiliki nilai signifikansi (Sig) = 0,000 < 0,05 dan besarnya koreksi kurva thorakal memiliki nilai koefisien regresi lebih besar bila dibandingkan dengan lumbal modifier terhadap koreksi spontan kurva lumbal paska operasi (variabel besar koreksi kurva thorakal (X1) = 0,764, Lumbal modifier (X2) = 0,092). Besarnya koreksi kurva thorakal berpengaruh signifikan terhadap koreksi spontan kurva lumbal paska operasi dan besarnya koreksi kurva thorakal yang paling dominan dalam mempengaruhi koreksi spontan kurva lumbal dibandingkan dengan lumbal modifier.Kata kunci : Adolescent idiopathic scoliosis, Lumbal modifier, kurva thorakal Adolescent idiopathic scoliosis Lenke I, main thoracic curve pattern has the major curve, with the proximal thoracic and thoracolumbar/lumbar being non structural minor curves. Thus, instrumentation and fusion of the main thoracic region alone is recommended. In the literature it is said that the lumbar curve spontaneously corrects to balance the thoracic curve after selective thoracic fusion. Most authors assumed a mechanism whereby improvement of the lumbar curve occurred through counterbalancing the surgical correction of the thoracic curve. The lumbar curve divided in three subgroups: lumbar modifier A, B and C. The selection of specific operative treatments depends on this modifier. This study was an observational analysis in 35 adolescent idiopathic scoliosis Lenke I patients after correction and posterior instrumentation surgery. Evaluation using X-rays before and after surgery to determine the type of lumbar modifier, the magnitude of the main thoracic curve and assessment of spontaneous lumbar curve correction, then correlation test obtained. The magnitude of main thoracic curve correction to the spontaneous lumbar curve correction has a significance value (Sig) = 0.000 < 0.05 and the magnitude of main thoracic curve correction has a greater regression coefficient than the lumbar modifier for spontaneous lumbar curve correction (large correction variable thoracic curve (X1) = 0.764, Lumbal modifier (X2) = 0.092). The magnitude of main thoracic curve correction has a significant effect on the spontaneous lumbar curve correction and the magnitude of main thoracic curve correction is most dominant factor to influence spontaneous lumbar curve correction compared to the lumbar modifier.Keywords: Adolescent idiopathic scoliosis, Lumbar modifier, main thoracic

Abstract:
Spinal stiffness and mobility assessments vary between clinical and research settings, potentially hindering the understanding and treatment of low back pain. A total of 71 healthy participants were evaluated using 2 clinical assessments (posteroanterior spring and passive intervertebral motion) and 2 quantitative measures: lumped mechanical stiffness of the lumbar spine and local tissue stiffness (lumbar erector spinae and supraspinous ligament) measured via myotonometry. The authors hypothesized that clinical, mechanical, and local tissue measures would be correlated, that clinical tests would not alter mechanical stiffness, and that males would demonstrate greater lumbar stiffness than females. Clinical, lumped mechanical, and tissue stiffness were not correlated; however, gradings from the posteroanterior spring and passive intervertebral motion tests were positively correlated with each other. Clinical assessments had no effect on lumped mechanical stiffness. The males had greater lumped mechanical and lumbar erector spinae stiffness compared with the females. The lack of correlation between clinical, tissue, and lumped mechanical measures of spinal stiffness indicates that the use of the term “stiffness” by clinicians may require reevaluation; clinicians should be confident that they are not altering mechanical stiffness of the spine through segmental mobility assessments; and greater resting lumbar erector stiffness in males suggests that sex should be considered in the assessment and treatment of the low back.

The lack of a software containing these methods motivated us to the development of the user friendly software package LUMPAC. And indeed, LUMPAC is slowly popularising the use of these theoretical methodologies - methodologies that are being put to more frequent tests, and are, consequently, slowly revealing their limitations. In this sense, we identified which aspects of the methods would deserve a more special attention, namely: intensity parameters calculations (Ωλ), calculation of the excited state energies of the ligands, and the calculation of the non-radiative decay rate (Anrad). The overall objective of this doctoral work is to correct some of these limitations as wellastoadvancenewdevelopments. RegardingtheΩλ calculation,wemitigatedthisproblem with a new way to adjust the charge factors and polarizabilities through a procedure we called theQDC Uniqueness Model, which makes use of a fairly small set of adjustaeble parameters (Q,D, andC). The importance of theQDC adjustment is that all derived quantities become also unique for a given complex geometry, including the chemical partition of the radiative emission rate (Arad) in terms of the effects of the ligands, which is being advanced here. To demonstrate one of the possible applications of this chemical partition, we address the case of repeating non-ionic ligand ternary complexes of europium(III) with DBM, TTA, and BTFA. The chemical partition perfectly ordered the non-obvious combination of pairs of non-ionic ligands that led to the mixed ligand compounds with the highest values ofAexp rad . Regarding the calculation of the excited states of the ligands, a new parametrization of the CIS method based on the NDDO approximation is being proposed, exclusively for lanthanide complexes. In addition, we carried out a study to evaluate some TDDFT methodologies for the calculation of excited states of ligands in lanthanide complexes. Among the functionals and basis sets evaluated, the combination LC-ωPBE/6-31G(d) was the one that led to the lowest UME (unsigned mean error), of around 1600 cm−1, for the triplet energies in comparison with data from the literature. The parametrization of the NDDO-CIS model implemented into ORCA provided a semiempirical method for the triplet energy calculation of lanthanide complexes with better predictionpower thanthebestassessed TDDFT method.

Abstract:
Lanthanide-containing systems have many applications, which extend from the biomedical field to optical images areas. Because of that, such systems have attracted the attention of several research groups around the world. It is indisputable that theoretical tools can provide useful information for the understanding of the phenomena that are not easily explained by using only experimental data. Moreover, the theoretical tools are useful for design new systems. Although several tools for the study of lanthanide complexes have been developed since the early 90 s, their use is still limited on account of these tools not being implemented into a userfriendly, free of charge computational package for the scientific community. In this context, the development of LUMPAC (LUMinescence PACkage) is inserted. With this new tool, we hope to enable experimental research groups to use theoretical tools on projects involving systems that contain lanthanide ions. In this dissertation, the methods implemented into LUMPAC are described in detail, given the user a good understanding of them. A short description on LUMPAC is introduced to provide an overview of the features that are implemented in the package. Furthermore, a detailed manual treating all the modulus of LUMPAC is available as an appendix. The LUMPAC project started in 2008. During its development, the program was applied in many different kinds of study involving lanthanide systems, as will be shown in a chapter of this dissertation. The network of collaboration among the Pople Laboratory with some research groups of prestigious universities allowed all these applications. This way, it is then possible to have an idea about some kinds of study in which the program can be applied. So far, LUMPAC is the only software that enables the study of luminescent properties of lanthanide-containing systems, being available free of charge at the following site: http://www.lumpac.pro.br.<br>Os sistemas contendo íons lantanídeos apresentam diversas aplicações, as quais se estendem desde a área biomédica até a de imagem ótica. Em decorrência disso, a busca por tais sistemas tem atraído a atenção dos mais diversos grupos de pesquisa em todo o mundo. É incontestável que as ferramentas teóricas podem fornecer informações úteis para o entendimento de fenômenos que não são explicados simplesmente com base em dados experimentais. Além disso, as ferramentas teóricas são úteis para o planejamento de novos sistemas. Apesar de diversas ferramentas para o estudo de compostos lantanídicos terem sido desenvolvidas desde o início da década de 90, o seu uso ainda é limitado devido ao fato dessas ferramentas não estarem implementadas em um pacote computacional de fácil uso e disponível gratuitamente para a comunidade científica. É nesse contexto em que o desenvolvimento do LUMPAC (LUMinescence PACkage) está inserido. Com o LUMPAC espera-se difundir o uso de tais métodos teóricos por grupos de pesquisa, sobretudo os experimentais, que concentram seus esforços em entender e projetar novos dispositivos luminescentes a base de lantanídeos. Nesta dissertação, as metodologias que estão implementadas no LUMPAC encontram-se apresentadas de maneira pormenorizada, conferindo ao usuário do software uma maior transparência com relação aos métodos. Uma descrição geral do LUMPAC é apresentada com a finalidade de fornecer uma ideia geral dos recursos que já estão implementados no pacote. Além do mais, um manual bastante detalhado tratando todos os módulos que compreendem o programa é disponibilizado como anexo. O projeto de desenvolvimento do LUMPAC teve início em 2008. Durante o processo de desenvolvimento do pacote, o programa encontrou uma vasta área de aplicação decorrente da rede de colaboração entre o laboratório Pople com alguns grupos de pesquisa de universidades renomadas do país. Através da apresentação dessas aplicações é possível ter uma ideia acerca dos diversos tipos de estudos em que o programa pode ser aplicado. Até o momento, o LUMPAC é o único software desenvolvido que permite o estudo de propriedades luminescentes de sistemas contendo íons lantanídeos, sendo disponibilizado gratuitamente no seguinte endereço eletrônico: http://www.lumpac.pro.br.

Abstract:
Due to the mathematical complexity of current musculoskeletal spine models, there is a need for computationally-efficient models of the intervertebral disc (IVD). The aim of this study is to develop a mathematical model that will adequately describe the motion of the IVD under axial cyclic loading and three-dimensional quasi-static loading as well as maintain computational efficiency for use in future musculoskeletal spine models. <p> A viscoelastic standard nonlinear solid (SNS) model is introduced within this study. It was developed to predict the axial response of the human lumbar IVD subjected to low-frequency vibration. Nonlinear axial behavior of the SNS model was simulated by a strain-dependent elastic modulus on the standard linear solid (SLS) model. <p> The SNS model was able to predict the dynamic modulus of the IVD for frequencies of 0.01, 0.1, and 1 Hz. Furthermore, the model was able to quantitatively predict the load relaxation at a frequency of 0.01 Hz. However, model performance was unsatisfactory when predicting load relaxation and hysteresis at higher frequencies (0.1 Hz and 1 Hz). Results suggest that the standard solid model may require strain-dependent elastic and viscous behavior to represent the dynamic response to compressive strain. <p> The SNS model was expanded to a three-dimensional elastic model by adding a matrix of spring elements in parallel with the SNS model. The geometry and orientation of the added elements represent the regional variations in stiffness and physiologic fiber angle. Results suggest that lordotic posture may be advantageous when modeling the intervertebral joint (IVJ) behavior.<br>Master of Science

Veremos que Lumpy Gravy nos auxilia, em sua montagem, na direção de tal concepção ao colocar em jogo o núcleo de negatividade que encontra-se no fazer humano. Abordaremos a obra de arte através do processo de sublimação, termo psicanalítico aqui trabalhado conforme a elaboração de Jacques Lacan no Seminário 7: a ética da psicanálise (2008). A sugestão aqui construída é de que Lumpy Gravy opere na sublimação de seu suporte material, sua condição arquívica, enquanto seu sintoma. Para isso conjugaremos a noção de sinthoma lacaniano com a sismografia de Warburg. A obra de arte encontra-se no leitor, o que quer dizer que ela encontra-se na formação de um olhar. O presente estudo é uma tentativa de elaboração sobre o olhar de Lumpy Gravy.<br><br>Abstract : While studying Frank Zappa?s Lumpy Gravy, what we?re trying to develop is a notion of living work of art, made subject, that maintains its flux while letting its master go dumb. We?ll see that Lumpy Gravy helps us, in its montage, in the direction of such a concept while putting in stake the very core of negativity that is found in human craft. We?ll take the work of art through the process of sublimation, psychoanalytic term here studied according to the elaboration of Jacques Lacan in its Seminary Book 7. The suggestion here built is that Lumpy Gravy operates in the sublimation of its material support, its archival condition, as its symptom. For that we?ll work the notion of lacanian sinthome with Warburg?s seismography. The work of art is found in the reader, which means it is found in the craft of a gaze. This study if an attempt to elaborate on the gaze of Lumpy Gravy.

Abstract:
Offshore pipelines are usually buried to protect the pipe from external loads. When trenching is achieved by jetting or ploughing, some clayey soils can be cut into distinct lumps and this lumpy soil is then used as the backfill material under which the pipe is buried. To counter the effects of upheaval buckling, the resistance of the soil to pipe uplift must be known. There is still uncertainty about the performance of lumpy backfill in this regard. A series of centrifuge tests were performed with such soils as backfill, utilising a specially designed pore-pressure measuring pipe, to determine the influence of lump size, lump shape and pullout rate on uplift resistance Backfill comprising larger lumps consolidates quicker than if the backfill lumps are smaller. It is also observed that backfill comprising larger lumps provides greater resistance to pipe uplift after consolidation.

Abstract:
Abstract Thermal transients of single-row finned-tube serpentine liquid-to-gas cross-flow heat exchangers utilizing single phase fluids are examined numerically in the temperature-time domain. Two modeling approaches are examined with the aim of contrasting levels of modeling sophistication for this specific heat exchanger application. One model is axially lumped (cases with more than one lump are examined), and the second model is axially distributed. The lumped model is solved using a 4th order Runge-Kutta integration scheme, and the distributed model is solved using an explicit upwind differencing scheme. Single lump representation is found to be undesirable, while multi-lump representation provides adequate comparison with the distributed model. Computation times become an issue for the lumped model if multiple lumps are solved using the 4th order Runge-Kutta scheme.
