Abstract:
Neutron powder diffraction data, collected over the temperature range 10–770 K, have been analysed in order to make a detailed characterization of the sequence of phase transitions occurring in the Hf-rich ferroelectric PbHf0.8Ti0.2O3, titanium hafnium lead oxide. Over the whole temperature range this compound undergoes two phase transitions, which involve cationic displacements and octahedral deformations (tilt and/or distortion) leading to strongly distorted perovskite-type structures. The first transition appears around 415 K between two ferroelectric rhombohedral phases: a low-temperature nonzero-tilt phase F RL (space group R3c) and an intermediate zero-tilt phase F RH (space group R3m). The second one, detected around 520 K, is associated with a ferroelectric to-paraelectric transition between the F RH phase and the P C cubic phase (space group Pm3¯m). From high-resolution neutron powder diffraction data (diffractometer 3T2-LLB, Saclay, France, λ = 1.2251 Å), the crystallographic structure of the three successive phases has been accurately determined at the following temperatures: T = 10 K (F RL): space group R3c, Z = 6, a hex = 5.7827 (1), c hex = 14.2702 (4) Å, V hex = 413.26 (2) Å3; T = 150 K (F RL): space group R3c, Z = 6, a hex = 5.7871 (1), c hex = 14.2735 (4) Å, V hex = 413.98 (3) Å3; T = 290 K (F RL): space group R3c, Z = 6, a hex = 5.7943 (1), c hex = 14.2742 (5) Å, V hex = 415.04 (3) Å3; T = 440 K (F RH): space group R3c, Z = 6, a hex = 5.8025 (1), c hex = 14.2648 (4) Å, V hex = 415.94 (3) Å3; T = 520 K (P C ): space group Pm3¯m, Z = 1, a cub = 4.1072 (2) Å, V cub = 69.29 (1) Å3. In addition, a neutron powder thermodiffractometry experiment, performed between 290 and 770 K (diffractometer D1B-ILL, Grenoble, France, λ = 2.533 Å), has been used to study in situ the temperature-induced phase transitions. From sequential Rietveld refinements, the temperature dependence of the cation displacements and the rotation and/or distortion of oxygen octahedra was derived.

Abstract:
Voltage-gated sodium channels mediate the initiation and propagation of action potentials in excitable cells. Transmembrane segment S4 of voltage-gated sodium channels resides in a gating pore where it senses the membrane potential and controls channel gating. Substitution of individual S4 arginine gating charges (R1–R3) with smaller amino acids allows ionic currents to flow through the mutant gating pore, and these gating pore currents are pathogenic in some skeletal muscle periodic paralysis syndromes. The voltage dependence of gating pore currents provides information about the transmembrane position of the gating charges as S4 moves in response to membrane potential. Here we studied gating pore current in mutants of the homotetrameric bacterial sodium channel NaChBac in which individual arginine gating charges were replaced by cysteine. Gating pore current was observed for each mutant channel, but with different voltage-dependent properties. Mutating the first (R1C) or second (R2C) arginine to cysteine resulted in gating pore current at hyperpolarized membrane potentials, where the channels are in resting states, but not at depolarized potentials, where the channels are activated. Conversely, the R3C gating pore is closed at hyperpolarized membrane potentials and opens with channel activation. Negative conditioning pulses revealed time-dependent deactivation of the R3C gating pore at the most hyperpolarized potentials. Our results show sequential voltage dependence of activation of gating pore current from R1 to R3 and support stepwise outward movement of the substituted cysteines through the narrow portion of the gating pore that is sealed by the arginine side chains in the wild-type channel. This pattern of voltage dependence of gating pore current is consistent with a sliding movement of the S4 helix through the gating pore. Through comparison with high-resolution models of the voltage sensor of bacterial sodium channels, these results shed light on the structural basis for pathogenic gating pore currents in periodic paralysis syndromes.

Abstract:
The XTiO3 (X = Mn, Fe, Co and Ni) materials with R3c structure could be grown under critical conditions based on first-principles calculations and thermodynamic stability analysis. FeTiO3 and MnTiO3 could be synthesized relatively easily under metal-rich and O-poor conditions, while NiTiO3 could be stable under Ni-rich, O-rich and Ti-poor conditions. The predicted R3c CoTiO3 under thermodynamic equilibrium conditions is suggested to be synthesized under Co-rich, O-rich and Ti-poor conditions, but the calculated phonon dispersion indicates R3c CoTiO3 becomes unstable under the dynamical conditions. The ferroelectric behavior in the XTiO3 (X = Mn, Fe, Co and Ni) system could be dominated by the Ti ion with d0 state and the strong hybridization between Ti and O, while the magnetic property is mainly caused by the contribution of 3d transition metal.

Pure BiFeO3 ceramics and BiMnxFe1-xO3 (x=0.1, 0.15, 0.2, and 0.25) ceramics were prepared by sol-gel method. A structural phase transition from rhombohedral R3c to triangle R3m occurred in Mn-doped BFO ceramics. Mn-doped BFO ceramics exhibited better crystallinity, larger dielectric constant as well as smaller dielectric loss. Besides, a small nonlinearity of magnetization-field curves M(H) was observed, the remanent magnetization increased with the increase of manganese content, and all the BiMnxFe1-xO3 ceramics showed the typical antiferromagnetic, which could be attributed to the effective decrease in the concentration of oxygen vacancies, and the corresponding structural transition.

Detailed structural properties of La1−xBaxCoO3 (LBCO) have been investigated by means of X-ray powder diffraction and Rietveld analysis. A structural phase transformation from R3c to Pm3m at x=0.30–0.35 has been detected based on a comparison between the refinements of R3c and Pm3m. The Co–O bond length of the CoO6 octahedron expanded rapidly with increasing Ba content when x<0.1, and then it leveled off and kept constant at 0.1⩽x⩾0.35, where the Co–O–Co bond angle reaches 180°. The Co–O bond length expansion resumed with increasing Ba content beyond x=0.35.

O multiferroísmo consiste na existência simultânea de ordenamento magnético e propriedades ferroelétricas ou ferroelásticas em uma mesma fase cristalina do material. O tipo mais comum de material multiferróico apresenta um acoplamento entre as propriedades ferroelétricas e magnéticas, também chamado de acoplamento magnetoelétrico. No presente trabalho, novos materiais multiferróicos foram propostos através da substituição de cátions A e B na estrutura cristalina R3c por átomos magnéticos e não magnéticos e investigados por meio de simulações computacionais baseadas na Teoria do Funcional de Densidade. Os materiais investigados apresentam alta estabilidade em condições ambientes e em altas pressões, bem como propriedades eletrônicas e ópticas que sugerem estes como alternativas viáveis para desenvolvimento de dispositivos eletrônicos e aplicação em processos de fotodegradação e técnicas de water splitting fotocatalítico. Sobretudo, as propriedades magnéticas e ferroelétricas são orientadas ao longo das direções [111] e x ([100]), respectivamente, evidenciando um comportamento anisotrópico no material. Assim sendo, tais propriedades são tangenciais entre si mostrando a possibilidade de um controle destas a partir de campo elétrico aplicado na direção [111] resultando na perturbação do ordenamento magnético ou por meio de um campo magnético aplicado na direção x para obter uma resposta ferroelétrica do material. A estes fatos apresentados, os resultados obtidos também evidenciam uma origem molecular do acoplamento magnetoelétrico não só em estrutura R3c, mas em quaisquer outras estruturas cristalinas, uma vez que pode-se concluir que a origem molecular das propriedades multiferróicas consiste na existência de propriedades tangenciais e dependentes ao longo da célula unitária do material, sendo que tal dependência sugere o acoplamento entre estas. De tal modo, o presente trabalho representa uma primeira descrição teórica ampla de como tais propriedades são observadas nos materiais investigados em função da modificação química da estrutura cristalina, além da descrição das propriedades gerais dos materiais propostos, apontando estes como alternativas em potencial para desenvolvimento de dispositivos eletrônicos e quaisquer aplicações baseadas no multiferroísmo ou em materiais inteligentes.<br>The development of materials aiming technological applications has been the focus of several scientific manuscripts and, among investigated materials stands out the multiferroics, which are considered as the next generation of materials to smart devices development. The multiferroism consists on the simultaneous existence of a magnetic ordering and ferroelectric or ferroelastic properties in a same crystalline phase, being the most common kind of multiferroism observed between the ferroelectricity and the magnetics ordering and also known as magnetoelectric coupling. In this work, new multiferroic materials were proposed from A and B cations replacement in R3c structures by magnetic and non-magnetic atoms; the materials were evaluated by computational simulations based on Density Functional Theory. The investigated materials presents high stability under room condition and high pressures in R3c structures, as well as electronic and optical properties suggesting then as viable alternatives to development of electronic devices and photocatalytic process, such as water splitting and photodegradation. Moreover, the ferroelectric and magnetic properties are oriented on [111] and x ([100]) directions, respectively, showing an anisotropic behavior in the material. Thus, such properties are tangent each other indicating the control possibility from an electric field applied along [111] direction resulting on a magnetic response or from a magnetic field applied along x direction to obtain a ferroelectric response. Therefore, the obtained results clarify the molecular origin of the magnetoelectric coupling for R3c materials and any other crystalline structures since the coupling arises from the fact that the magnetism and ferroelectricity are tangent each other and, consequently, dependents, indicating the coupling between both properties. This work represents the first deep description of how the multiferroism can be affected by chemical modification and also the first report about the general properties of evaluated materials, indicating these materials as potential alternative to development of electronic devices and any application based on multiferroism or smart materials.

No presente estudo, propomos a investigação teórica, baseada na Teoria do Funcional de Densidade, dos materiais ATiO3 (A = Mn, Fe, Ni) na estrutura R3c com objetivo de esclarecer o efeito da substituição do cátion A sobre as propriedades estruturais, magnéticas e eletrônicas, bem como descrever diferentes mecanismos de controle das propriedades multiferróicas baseados em arquiteturas de filmes-finos, morfologia e controle de defeitos intrínsecos. Para uma maior compreensão dos efeitos envolvidos nos materiais ATiO3, diferentes funcionais de troca e correlação foram investigados e o funcional PBE0 apresentou os menores desvios, consequentemente, a melhor representação comparado aos resultados experimentais. Com objetivo de investigar as propriedades conectadas a filmes-finos dos materiais ATiO3, propomos uma metodologia inovadora que permite descrever as deformações uni- e biaxial que se originam na região de interface entre o filme e o substrato. Nesse caso, os resultados obtidos indicam que as distorções estruturais induzem uma transição magnética para o NiTiO3, originando ordenamento ferromagnético a partir de um critério magneto-estrutural associado a deformação dos clusters [MO6] que reproduz satisfatoriamente os resultados experimentais reportados na literatura. De modo análogo, para elucidar a relação entre o magnetismo e a morfologia dos materiais ATiO3, combinamos cálculos de Energia de Superfície, Construção de Wulff e um formalismo avançado para descrever o magnetismo superficial considerando a existência de spins não compensados ao longo dos planos polares (100), (001), (101), (012), (111) e apolares (110). Os resultados indicam que a redução do número de coordenação dos metais A e Ti para os planos (001) e (111) resulta na transferência de carga entre os cátions A2+ e Ti4+, originando espécies Ti3+ magnéticas que aumentam o magnetismo superficial ao longo desses planos. Além disso, esse efeito é capaz de induzir uma alteração do caráter eletrônico para esses materiais, permitindo indicar que a clivagem das superfícies contribui para o controle das propriedades eletrônicas, reduzindo o valor de band-gap ou gerando comportamento meio-metálico. Os mapas morfológicos obtidos indicam que o controle da exposição majoritária do plano (001) para obtenção de discos hexagonais induz um aumento do magnetismo superficial para os materiais ATiO3 em acordo com resultados experimentais, além de predizer diferentes morfologias acessíveis com interessantes propriedades magnéticas. Ademais, o efeito de defeitos intrínsecos como vacâncias de oxigênio no bulk e superfície apolar (110) dos materiais ATiO3 foi investigado indicando que a redução do número de coordenação na região do defeito induz que os elétrons remanescentes sejam localizados, principalmente, nos orbitais 3d vazios dos cátions Ti vizinhos, gerando espécies [TiO5]ꞌ e [TiO4]ꞌ (3d1 ) que possibilitam uma interação ferromagnética nos materiais MnTiO3 e FeTiO3. A combinação entre os diferentes mecanismos investigados permitiu estabelecer um guia científico para o estudo teórico de materiais multiferróicos, contribuindo para descrever as potencialidades dos diferentes materiais bem como predizer novos candidatos.<br>The development of spintronic has motivated the search for new multiferroic materials due to the multifunctionality of these materials that are associated with the coupling of different ferroic orders into a single crystalline structure. In the present study, we propose a theoretical investigation, based on Density Functional Theory, of ATiO3 (A = Mn, Fe, Ni) materials in the R3c structure in order to clarify the effect of A-site cation replacement on the structural, magnetic and electronic properties, as well as to describe a different mechanism to control the multiferroic properties based on thin-film architectures, morphology and point defects. For a more comprehensive overview of the main effects involved on the ATiO3 materials several exchange-correlation functionals were investigated, being the PBE0 the functional with smallest deviations and, consequently, the best representation in comparison to the experimental results. Aiming to describe the main fingerprints related with the creation of ATiO3 thin-films, we propose an innovative methodology that allows to describe the uniaxial and biaxial deformations originated in the interface region between the film and the substrate. In this case, the results indicate that structural distortions induce a magnetic transition for the NiTiO3, originating ferromagnetic ordering from magneto-structural criteria, which is associated to the deformation of the [MO6] clusters that reproduces satisfactorily the experimental results reported in the literature. Similarly, in order to elucidate the relationship between the magnetism and the morphology of the ATiO3 materials, we combined Surface Energy, Wulff Construction, and an advanced formalism to describe surface magnetism by considering the existence of uncompensated spins along the polar planes (100), (001), (101), (012), (111) and non-polar (110). The results indicate that the reduction of the coordination for both A and Ti metals along the (001) and (111) planes induces a charge transfer between the A 2+ and Ti4+ cations, resulting in magnetic Ti3+ species that increase the superficial magnetism along such planes. Moreover, this effect allowed a change in the electronic structure for these materials, allowing to point out that the cleavage of the surfaces contribute to the control of the electronic properties reducing the band-gap value or generating half-metallic behavior. The morphological maps indicated that the control of the major exposure for the (001) surface to obtain hexagonal discsinduces an increase of the superficial magnetism for the ATiO3 materials according to experimental results, besides predicting different accessible morphologies with interesting magnetic properties. In addition, the effect of intrinsic defects such as oxygen vacancies on the bulk and non-polar (110) surface of the ATiO3 materials were investigated, indicating that the reduction of coordination in the defect region induces the localization of the remaining electrons in the empty 3d orbitals of neighboring Ti cations, generating [TiO5]'and [TiO4]' (3d1 ) species that allow a ferromagnetic interaction for MnTiO3 and FeTiO3 materials. The combination of the different mechanisms investigated has allowed to stablish a scientific guide for the theoretical study of multiferroic materials, contributing to describe the potentialities of the different materials as well as to predict new candidates.

Abstract:
RFC plays an essential role in DNA replication by loading the sliding clamp PCNA onto DNA in order to tether DNA polymerase δ to DNA. RFC consists of five subunits, one large subunit and four small subunits. The large subunit of RFC contains an extended C-­terminal domain that is not present in the small subunits and whose function remains unknown. In addition to RFC, eukaryotic cells contain two more putative PCNA loaders known as RLCs. These other PCNA loaders have similar structures to RFC and contains the RFC small subunits, however the large subunit is replaced with a different protein, either Elg1 or Ctf18. The function of the three PCNA loaders is not clear. In this work the function of the Rfcl C-terminal domain (CTD) was examined. The analysis of an Rfcl CTD deletion mutant showed that the domain is essential for cell viability. <i>rfcl-44, </i>a temperature-sensitive mutant with a mutation in the C-terminal domain, displayed sensitivity to DNA damaging agents, abnormal chromosome structure and a synthetic lethal phenotype when combined with DNA replication mutants. <i>rfc5 </i>mutants were isolated as suppressors of <i>rfcl-44 </i>suggesting that the defect in <i>rfcl-44 </i>may be in the Rfcl-Rfc5 interaction. Ctf18, Dccl and Ctf8, components of Ctf18-RLC, were required for the viability of <i>rfc1­-</i>44 whilst Elg1 was not. Deletion of Elg1 restored the viability of <i>rfc1-44 ctf18</i><i>Δ</i><i> </i>double mutant cells, suggesting that Elg1 plays a negative role. The negative role of Elg1 was confirmed by over-expression of Elg1 in <i>rfc1-44 </i>cells showing a lethal phenotype at permissive temperature. These results suggest that RFC plays a key role in DNA replication and that Elg1-RLC and Ctf18-RLC can play negative and positive roles respectively when RFC function is impaired.

The ROC (Receiver Operating Characteristic) curve is a projection of two different cumulative distribution functions F0 and F1. On axis are values 1-F0(c) and 1-F1(c). The c-parameter is a real number. This curve is useful to check quality of discriminant rule which classify an object to one of two classes. The criterion is a size of an area under the curve. To solve real problems we use point and interval estimation of ROC curves and statistical hypothesis tests about ROC curves.

Abstract:
Reactive powder composites (RPC) have been recently a subject of many researches of modern concrete technology. This type of concrete is very fine and its behaviour exceeds the other types of concrete, therefore there are new possibilities of its use. The design and production of RPC is complex technology process which needs to gain new results in RPC research to get the best features regarding its higher price. This thesis is focused on design of reactive powder concrete (RPC200), which compressive strength is between 200 – 300 MPa. Next goal is to prove the influence of curing regimes like high temperature or pressure, and also check the possibilities of production of low cement reactive powder composite (LCRPC).

Abstract:
<p>The majority of all power cuts that affects individuals and communities are caused by earth faults on the power transmission lines at 10kV and 20kV level [1]. If these power cuts could be eliminated, less disturbances and interrupts would lead to large amounts of money savings.</p><p>Swedish Neutral has developed such a protection system. When an earth fault occurs power is injected into the neutral point of the transformer. The RCC (Residual Current Compensation) protection calculates a compensation current exactly 180 degrees out of phase to the fault current.

Here, some advantages are envisioned: bandwidth aggregation, the ability to maintain the connection, if one of the network path fails and the use of multiple paths. To extend these capabilities to the application, RFC 6897 defines an API to better control each of MPTCP’s subflows, so that these can be added or removed as needed. This work presents an initial API implementation as defined in RFC 6897. We implemented some functions described in the document, such as protocol on/o, check existent subflows and add new subflows. To test the API and validate our implementation we built an HTTP application that detects elephant flows and uses the API for open new subflows using the original TCP connection. Some tests were performed in a network using a cubic topology and showed that the API utilization decreased the Flow Completion time of TCP connections.<br>O protocolo Multipath TCP (MPTCP) permite que as aplicações possam explorar melhor os recursos de rede disponíveis para dispositivos multiconectados como os telefones móveis ou sistemas multi-homed. Aqui, algumas vantagens são previstas: agregação de banda, a habilidade de manter a conexão estabelecida se houver falha em um dos caminhos de rede e a utilização de múltiplos caminhos. Para estender essas capacidades para a aplicação, a RFC 6897 define uma API que permite um melhor controle de cada subfluxo MPTCP, de modo que esses possam ser adicionados ou removidos conforme necessário. Este trabalho apresenta uma implementação inicial da API descrita na RFC 6897 para o protocolo MPTCP. Sendo assim, implementamos algumas das funções de manipulação do protocolo MPTCP descritas no documento, quais sejam: ligar e desligar o protocolo, verificar subfluxos existentes e adicionar novos subfluxos. Para testar a API e validar a nossa implementação, nós desenvolvemos uma aplicação HTTP que detecta fluxos elefantes e utiliza a API para abrir novos subfluxos a partir da conexão TCP original. Testes de desempenho foram realizados em uma topologia cúbica e mostraram que a utilização da API pela aplicação diminuiu o Flow Completion Time das conexões TCP.

Abstract:
For the application of waste heat recovery (WHR), supercritical CO2 (S-CO2) Brayton power cycles offer significant suitable advantages such as compactness, low capital cost and applicable to a broad range of heat source temperatures. The current study is focused on thermodynamic modelling and optimization of Recuperated (RC) and Recuperated Recompression (RRC) S-CO2 Brayton cycles for exhaust heat recovery from a next generation heavy duty simple cycle gas turbine using a genetic algorithm. The Genetic Algorithm (GA) is mainly based on bio-inspired operators such as crossover, mutation and selection. This non-gradient based algorithm yields a simultaneous optimization of key S-CO2 Brayton cycle decision variables such as turbine inlet temperature, pinch point temperature difference, compressor pressure ratio. It also outputs optimized mass flow rate of CO2 for the fixed mass flow rate and temperature of the exhaust gas. The main goal of the optimization is to maximize power out of the exhaust stream which makes it single objective optimization. The optimization is based on thermodynamic analysis with suitable practical assumptions which can be varied according to the need of user. Further the optimal cycle design points are presented for both RC and RRC configurations and comparison of net power output is established for waste heat recovery.

Abstract:
Abstract The accelerating growth of electricity demand necessitates looking for potential waste heat recovery solutions in production industries. Significant potential for efficient waste heat recovery is observed in the cement manufacturing industry. Based on the waste heat source temperatures in a cement plant, two potential candidates, the supercritical CO2 Brayton (S-CO2) cycle or the Organic Rankine cycle (ORC), promises low capital cost and enhanced thermodynamic performance. The current study focuses on modelling and optimization of the S-CO2 and ORC cycles for a 1 MTPA cement plant, with the raw-clinker preheater as the waste-heat source. The primary objective is to maximize the net-power output using genetic algorithms. A comparative performance analysis of the two ORCs with working fluids: R134a and Propane, the simply recuperated S-CO2 cycle (RC) and recompressed-recuperated S-CO2 cycle (RRC) configurations is presented with varying number of preheaters. For all cases, ORC-R134a yields more power than the ORC-Propane, RC, and RRC configurations. In terms of the waste heat recovered, ORC-Propane marginally outperforms ORC-R134a. The ORC configurations recover 32%–38% of the available heat, while the S-CO2 configurations recover, at maximum, 25%–30% of the available heat.
